Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a² - b² =(a+b)(a−b) where a=x and b=3.
(x+3)(x-3)(x+1)(x-1)

Answer:
the awnser is 124 YW:)
Step-by-step explanation:
62x2=124
Answer:
124 / C
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. We know that angle k is 62, angle J is 90, that adds to 152. 180-152 gives us the third angle of the triangle as 28. Assuming that the two triangles are similar, the angle opposite of the 28 degree is also 28 degrees. The angles on the line should also add up to 180 degrees. So 180 - 28 - 28 = 124.

If x represents the length of the shortest shelf, which expression would represent the length of the longest shelf?
x + 6
x + 4
x + 3
Answer:
x+6
Step-by-step explanation:
The value of x is 12. Therefore, the shelves are 12, 14, 16, and 18 inches long. The longest shelf is x + 6.
Answer:
x+6
Step-by-step explanation:
The value of x is 12. Therefore, the shelves are 12, 14, 16, and 18 inches long. The longest shelf is x + 6.

Dante and Mia have 350 pennies in their piggy banks, altogether. After Dante lost half of his pennies and Mia lost one third of her pennies, they both had an equal amount of pennies left. How many pennies did they lose altogether?
Answer:
In total they both lost 150 pennies.
Step-by-step explanation:
Since Dante and Mia have 350 pennies in their piggy banks, altogether, and after Dante lost half of his pennies and Mia lost one third of her pennies, they both had an equal amount of pennies left, to determine how many pennies did they lose altogether the following calculation must be performed:
350 = 200 + 150
200 - (200/2) = 200 - 100 = 100
150 - (150/3) = 150 - 50 = 100
Therefore, in total they both lost 150 pennies.

Adrianna's bedroom has a perimeter of 14 meters. The width is 3 meters.
What is the length of her room?
Answer:
Adrianna's bedroom has a perimeter of 14 m/s. The width is 3 meters. What is the length of her room?
The answer is 4 meter (s)
Step-by-step explanation:
Hope the picture helps
The length of her room is 4 meters.
What is the perimeter of the room?The formula for the perimeter of a rectangle is (width + height) x 2.
Adrianna's bedroom has a perimeter of 14 meters.
The width is 3 meters.
Let, the length of her room be x.
The length of her room is;
[tex]\rm Perimeter \ of \ room =2 (Length +Width)\\\\14 =2(x + 3)\\\\14 = 14=2x+6\\\\2x=14-6\\\\2x=8\\\\x=\dfrac{8}{2}\\\\x=4[/tex]

Find the measure of each acute angle
Answer:
x = 18
Step-by-step explanation:
The sum of interior angles in a triangle = 180 degrees
The given is a right triangle which means one of the angle is = 90
so the sum of 3x + 2x = 90
5x = 90 divide both sides by 5
x = 18 to find the measure of angles replace x with 18
The mean temperature for the first 7 days in January was 3 °C.
The temperature on the 8th day was 7 °C.
What is the mean temperature for the first 8 days in January?
Answer:
3.5 °C
Step-by-step explanation:
To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.3 x 7 = 21
Add 21 and 8 together to get the sum of the temperatures in the first 8 days.21 + 8 =29
Divide 29 by 8 to get the mean temperature for the first eight days.29 ÷ 8 = 3.5

Can someone please help me with and explain this?
Answer:
A
Step-by-step explanation:
Point R is (1, 5).
The transformation (x + 1, y - 1) denotes a translation of one unit to the right and one unit downwards.
Simply add one to the x-coordinate and subtract one to the y-coordinate of R. Hence:
[tex]R'=((1)+1, (5) -1)=(2, 4)[/tex]
Next, we want to dilate RUST by a scale factor of three. Since the dilation is centered on the origin, we can simply multiply each coordinate by three. This yields:
[tex]R'=(3(2), 3(4))=(6, 12)[/tex]

Answer:
yes
Step-by-step explanation:
The triangles are given as right triangles. Hypotenuses QT and RS are given as congruent.
We also have XS ≅ TP. By the addition property of equality, this means ...
XS +ST ≅ ST +TP
By the segment sum theorem, this means ...
XT ≅ SP
XT and SP are the corresponding legs of the right triangles. So, we have corresponding hypotenuses and corresponding legs congruent. This lets us conclude ΔXQT ≅ ΔPRS by the HL theorem.
5. Today, everything at a store is on sale. The store offers a 20% discount.
a. The regular price of a T-shirt is $18. What is the discount price?
b. If the regular price of an item is x dollars, what is the discount price in dollars?
C. The discount price of a hat is $18. What is the regular price?
Answer:
Step-by-step explanation:
20% = 20/100 = 0.2
The amount you need to pay for a T shirt is
Cost = original amount(100% - 20%)
Original amount = 18
100% - 20% = 80%
80% = 80 / 100 = 0.8
What this means is that you will pay 80% of the original cost.
Cost = 18*0.8
Cost = $14.40
Part B
Cost = 0.8 * x
Part C
Selling price = 0.8*Original Cost
Selling price = 18
18 = 0.8 * x
18/0.8 = x
x = 22.5
The original price was $22.50

Surface area of rectangular prism length 6 in., width 5 in., height 12 in.
The surface area is 324
Answer:
The surface area of this rectangular prism is 324 [tex]inches^{2}[/tex].
Step-by-step explanation:
The formula for surface area of a rectangular prism is this :
A = 2(wl + hl + hw)
l = 6, w = 5, h = 12.
Now knowing these values, we can solve for A.
A = 2(wl + hl + hw) = 2(5 · 6 + 12 · 6 + 12 · 5) = 324
The surface area of this rectangular prism is 324 [tex]inches^{2}[/tex].
