If Perimeter is P=2l+2w then
2w=P-2l
therefore
w=(p-2l)/2

Which of the following expressions can be factored by grouping? (Select all that apply.)
Greeley [361]

Answer:

Options (3), (4) and (5)

Step-by-step explanation:

1). a² - 9a + 7ab + 63b

  = a(a - 9) + 7b(a + 9)

  Now we can not solve this problem further.

  Therefore, can't be factored by grouping.

2). 3a + 4ab - b - 12

   = a(3 + 4b) - 1(b - 12)

   We can't solve it further.

   Therefore, can't be factored by grouping.

3). ab + 6b - 2a - 12

   = b(a + 6) - 2(a + 6)

   = (b - 2)(a + 6)

  We can be factored this expression by grouping.

4). x³ + 9x²+ 7x + 63

   = x²(x + 9) + 7(x + 9)

   = (x² + 7)(x + 9)

   Therefore, the given expression can be factored by grouping.

5). ay² + a - y² - 1

  = a(y² + 1) - 1(y² + 1)

  = (a - 1)(y² + 1)

  This expression can be factored by the grouping method.

Options (3), (4) and (5) are the correct answers.

How to solve 3+4(-4-2)+5=-16
masha68 [24]

Answer:

-16=-16

Step-by-step explanation:

You would first do (-4-2) which would be (-6), after you would multiply (-6) by 4 which comes out to be -24, after you would add 3 which would look like this -24+3 but since its a negative it would come out to be -21 then you would do the same thing with 5, it would look like this -21 + 5 but since its negative it would be -16. I hope this helped :)
