(2x-5)(x+6)=0
either 2x-5=0 Or, x+6=0
2x-5=0
2x=0+5
x=5/2
x+6=0
x=0-6
x=-6
so x=5/2 , x=-6
f(x)=3x−4 Input is x=3 , Output is
f(x)=−4x+3 Input is x=−3 , Output is
f(x)=−x−1 Input is x=−4 , Output is
f(x)=x2 Input is x=5 , Output is
f(x)=3x−4 Input is x=3 , Output is
3X3-4= 5
f(x)=−4x+3 Input is x=−3 , Output is
4x-3 +3 = -9
f(x)=−x−1 Input is x=−4 , Output is
-(-4-1) =-(-5) =5
f(x)=x2 Input is x=5 , Output is
5x2=10

Can someone help me with this question?
Answer:
A = 20.25 sq units
Step-by-step explanation:
to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it
it appears the segment is 4.5 units so you would square that to get the area
A = 4.5²
A = 20.25

Answer:
See below.
Step-by-step explanation:
4.2 is 4 and 2 tenths.
4 is 40 tenths.
That means that 4.2 is 40 tenths plus 2 tenths, or 42 tenths.
First line: 4.2 / 6 = 42 tenths / 6
In the second line, we divide 42 tenths by 6. Since 42 divided by 6 = 7, then 42 tenths divided by 6 equals 7 tenths.
Second line: 4.2 / 6 = 7 tenths
In the third line, we write 7 tenths as a number. 7 tenths is the same as 0.7.
Third line: 4.2 / 6 = 0.7

Each of 7 students reported the number of movies they saw in the past year. Here is what they reported.
5, 17, 17, 7, 12, 16, 12
Send data to calculator
Find the mean number of movies that the students saw.
If necessary, round your answer to the nearest tenth.
0
movies
Х
5
?
Continue
Continue
Answer:
mean=12
Step-by-step explanation:
First, order the data like so.
5, 7, 12, 12, 16, 17, 17
Then add them all up.
It is a sum of 86.
Finally divide
86/7=12.2
Since 12.2 movies aren't possible, let's say the mean is 12

What's the area of this
Answer:
133
Step-by-step explanation:
Because the figure is an irregular figure we need to break it up into two regular figures
The figure would be broken into..
A square with a side length of 4
And a rectangle with a length 13 and a width of 9
We now find the areas of the regular figures and add them together to get our answer
For the square.
To find the area of a square simply square the side length
Area = 4^2 = 16
For the rectangle
to find the area of the rectangle simply multiply the Length by the width
Area = 13*9= 117
Finally add the two areas together to get the area of the composite figure
117 + 16 = 133
Lucky Lanes Bowling Alley is putting this design on its roof.
Enter the volume of this design in cubic feet.
=====================================================
Explanation:
The block on top has length, width and height of 4, 4 and 20-4 = 16.
The volume of this block is 4*4*16 = 256 cubic feet.
The volume of the block down below is 160 cubic feet because 10*4*4 = 160.
The total volume is therefore: 256+160 = 416 cubic feet

The solutions to the quadratic equation [tex]\rm x^2 + 2x = 25[/tex] is [tex]-1\pm \sqrt{26 }[/tex].
What is quadratic equation?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations.
The given equation is;
[tex]\rm x^2 + 2x = 25\\\\x^2+2x-25=0[/tex]
The solutions to the quadratic equation is determined by the following formula;
[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Where the value of a = 1, b = 2, and c = -25.
Substitute all the values in the formula;
[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\\rm x =\dfrac{-2\pm \sqrt{2^2-4\times 1\times (-25)} }{2\times 1}\\\\ x =\dfrac{-2\pm \sqrt{4+100} }{2}\\\\x =\dfrac{-2\pm \sqrt{104} }{2}\\\\x =\dfrac{-2\pm \sqrt{26 \times 2\times 2} }{2}\\\\x =\dfrac{-2\pm 2\sqrt{26 }}{2}\\\\x = 2 \times \dfrac{-1\pm \sqrt{26 }}{2}\\\\x=-1\pm \sqrt{26 }[/tex]
Hence, the solutions to the quadratic equation [tex]\rm x^2 + 2x = 25[/tex] is [tex]-1\pm \sqrt{26 }[/tex].

Find the cosine of ∠G (Must give explanation)
also why does my calculator say its undefined if I do the cos invert of (85/77) ??
cos^-1(85/77) = undefined ?? why
Answer:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
Step-by-step explanation:
Recall that cosine is the ratio of the adjacent side to the hypotenuse:
[tex]\displaystyle \cos(G)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]
The hypotenuse is always the side opposite to the right angle. In this case, it is
85.
The adjacent side to G is 36.
Therefore:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
For your other question, remember that in a right triangle, cosine is the ratio of the adjacent side to the hypotenuse.
As you know, the hypotenuse is always the longest side in a right triangle.
Therefore, the ratio of the adjacent side to the hypotenuse will never be greater than 1.
Since 85/77 is greater than 1, it is undefined.
The same applies to sine as well.
