<u>Answer</u>
D.25x2 – 36
<u>Explanation</u>
A. x² – 16x + 64
product = 64
sum = -16
factors: -8 and -8
x² – 16x + 64 = x² - 8x - 8x + 64
= x(x - 8) - 8(x - 8)
= (x - 8)(x-8) = (x-8)² ⇒ Not a difference of squares
B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares
C.9x² – x – 36
product = - 324
sum = -1
Factors: none
9x² – x – 36 ⇒ Has no perfect roots.
D.25x² – 36
25x² – 36 = (5x)² - 6² ⇒ This is the difference of squares.
Answer:
x = 12
Step-by-step explanation:
the two equations shown should add up to 180. so I did this equation: (10x-20)+ (6x+8) = 180 and I solved for x
Answer:
Perimeter of square Q is 49 inches.
Step-by-step explanation:
Let x be the length of side of square P and y be that of square Q.
It is given in the question that :

Also it is given that x=3.5 inches.Hence

∴ y=12.25 inches.
Perimeter of square Q is 4y =
inches.
Wdym by this LOL I don’t get it
Answer: It's between 10 and 11
It's closer to 11 than it is to 10.
This is because
after using a calculator.
You could also look at the list of perfect squares
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144,...}
The terms in bold are where 113 fits in between. So we can say,
