Answer:
3x^2-x-6
Step-by-step explanation:
f(x) = 3x^2 - 4
g(x) = x+2
(f - g)(x)= 3x^2 - 4-( x+2)
Distribute the minus sign
(f - g)(x)= 3x^2 - 4- x-2
Combine like terms
= 3x^2-x-6
Answer:
(f - g)(x) = 3 x² - x - 6
Step-by-step explanation:
Given :-
f(x) = 3x² - 4g(x) = x+2Find :-
(f - g)(x).Solution :-
(f - g)(x) = 3 x² - 4 - ( x + 2 )
Distribute the ( - ) minus sign
(f - g)(x) = 3 x ² - 4 - x - 2
Combine like terms
(f - g)(x) = 3 x ² - x - 4 - 2
(f - g)(x) = 3 x² - x - 6

Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees

Math help please due soon thanks
Answer with step-by-step explanation:
I'll use the list of referents you had on your other question and I believe this is a reference to that list.
Part A:
Use the reference of an adult stride (about 1 yard) to estimate the dimensions and length of the lawn edging. The dimensions can be used to find the area, in square yards, that is required to fill both sides of the flower beds.
Part B:
Similarly, you can use an adult stride of about 1 yard as a reference to measure to dimensions of the paved area and the dimensions of the brick. Using these dimensions, you can find area of the paved walkway and the area (surface area of top only) in square yards. Use these areas to find the approximate number of bricks needed to fill the walkway.

Solve for q. Write your answer as “q=___”
Answer:
7q-46= 3q +6
7q-3q = 6+ 46
4q= 52
4q/4= 52/4
q= 13
Answer:
Hello! q = 22
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees so...
22 × 7 = 154 154 - 46 = 108
3 × 22 = 66 66 + 6 = 72
108 + 72 = 180 therefore q = 22 hope that helps!

I really need help do can someone do it step by step so I can understand plzzzz
Answer:
96×pi ft³
Step-by-step explanation:
by the way, it is totally easy to search for formulas on the internet.
the volume of a cone is
Vc = pi×r²×height/3
we have been given the slant height (10 ft) and the lateral "wall" area of the cone (60×pi ft²).
this wall area is
Aw = pi×r×slant height
60×pi = pi×r×10
60 = r×10
6 = r
so, now we know r fuer the volume formula, and we need the height of the cone (the inner one).
we use Pythagoras
10² = r² + height²
100 = 36 + height²
height² = 64
height = 8 ft
so, now we use the main formula for the volume
Vc = pi×r²×height/3 = pi×6²×8/3 = pi×36×8/3 = pi×12×8 =
= 96×pi ft³
cubic feet ! it is a volume !

Which equation could be used to find the length of the hypotenuse?
Triangle A B C. Side A C is 5 centimeters and side C B is 8 centimeters. Hypotenuse A B is labeled c.
5 squared + 8 squared = c squared
5 squared + c squared = 8 squared
c squared minus 5 squared = 8 squared
8 squared minus 5 squared = c squared
Answer:
AC^2+BC^2= AB^2
So 5^2+8^2=c^2
5 squared + 8 squared = c squared

Which of the following is a rational number but not an integer?
188, 13 2/5, -4, or -51
Answer:
Option C
Step-by-step explanation:
Rational numbers are numbers of the form p/q, where p and q are integers and q not equal to zero.
Integers are number of the form p/q , where q = 1
Option A : 188 => integer and rational
Option B: 13 => integer and rational
Option C :2/5 => rational but not integer ( because q = 5 and not 1 )
Option D : - 51 => integer and rational
Answer:
13 2/5Step-by-step explanation:
As,
Integers includes whole numbers, and negative of the whole numbers.
And Rationals includes every fraction, Integers and negative fraction.
So,
188, -4, and 51 are both Integers and Rationals.
But,
Only 13 2/5 is a mixed fraction included only in rationals and not in Integers

A painting without its frame has a width 2.5 times its height, h, in inches. Its frame is 3 in. wide all along its perimeter. What is an expression for the area of the framed painting in terms of h? A. 2.5h2 B. 2.5h2 + 6 C. 2.5h2 + 36 D. 2.5h2 + 21h + 36
Answer:
2.5h^2 + 21h + 36
Step-by-step explanation:
Height = h
width = 2.5h
border = 3 in.
Overall height = h+6
Overall width = 2.5h+6
Overall area
= (h+6)(2.5h+6)
= 2.5h^2 + 15h + 6h +36
= 2.5h^2 + 21h + 36

Sheila, janice, and katen, working together at the same rate, can complete a job in 3 1/3 days. Working at the same rate, how much of the job could janice and caren do in 1 day
Answer:
Janice and Karen could do in 1 day:
20% of the job.Step-by-step explanation:
To identify how much of the job could janice and caren do in 1 day, first, we must find how much of the job make just 1 person at the same rate:
If three persons make a job in 3 1/3 days, 1 person make the job in x:
3 persons ⇒ 3 1/3 days or 10/3 days1 person ⇒ xThen:
[tex]x=\frac{1 person*\frac{10}{3}days }{3 persons}[/tex] (we cancel the unit "persons")[tex]x=\frac{\frac{10}{3}days }{3}[/tex]x = 10 daysJust a person would need 10 days to complete a job, now, we're gonna divide this value in 2 to obtain the time that need two persons to complete a job:
Time to complete a job between 2 persons = [tex]\frac{10}{2}days[/tex]Time to complete a job between 2 persons = 5 daysHow two persons need 5 days to complete a job (in this case, the two persons are Janice and Karen), we can make a simple rule of three to obtain the percentage made in 1 day:
5 days ⇒ 100% of a job1 day ⇒ xThen:
[tex]x=\frac{1*100}{5}[/tex] (you can use the % if you want, the result is the same)[tex]x=\frac{100}{5}[/tex][tex]x=20[/tex]As you can see, Janice and Karen just in a day could do 20% of the job.

For example, (x)(x)=x^2
Add the exponents of the variable to get the correct answer.
(k^3)(k^5)=k^8
Answer and Step-by-step explanation:
When two values have the same base, have exponents, and are being multiplied to each other, then we add together the exponents.
So, we are given k to the power of 3, which is multiplied by k to the power of 5. The powers (exponents) are added together to make 8, and the bases combine to be only one of the bases, being k.
So, we are left with the answer being [tex]k^8[/tex].
