Mathematics
1 answer:
Leokris [45]3 years ago

Answer:

D. 25x² - 20x + 4

Step-by-step explanation:

The formula for the area of a square is: A = s², where s = a side length of the square since all side lengths of a square are equal.  In this case, the side length is represented by '5x', so the original area is A = (5x)² = 25x².

Since Kelly is cutting off one inch from each side of square, this will actually take off 2 total inches from each side, making the new side length '5x - 2'.  We can now put this expression in for the values of 's' in our formula for area and use distributive property to solve:

A = (5x - 2)² = (5x - 2)(5x - 2)

Distribute using FOIL:  25x² - 10x - 10x +4 or 25x² - 20x + 4

Factor this equation , I can’t comprehend it
ivolga24 [154]

Answer:

B) (2x + 3)(2x - 3)

Step-by-step explanation:

Use the FOIL method for each answer choice.

FOIL = First, Outside, Inside, Last

(2x)(2x) = 4x²

(2x)(-3) = -6x

(3)(2x) = 6x

(3)(-3) = -9

4x² -6x +6x  -9

Simplify. Combine like terms:

4x² (-6x + 6x) - 9

4x² - 9

4x² - 9 = 4x² - 9 ∴ B) (2x + 3)(2x - 3) is your answer

What is the greatest common factor of 28, 48, and 64?
Goryan [66]
First, prime factor all of the numbers. Then, collect the factors which appear in all three lists:

28 = 2 x 2 x 7
48 = 2 x 2 x 2 x 2 x 3
64 = 2 x 2 x 2 x 2 x 2 x 2

The only factor which appears in all lists is 2. It appears twice in the first number, so the greatest common factor in the group is 2 x 2  = 4
