Brainers, please help me please
ra1l [238]

Answer:

W = 12

L = 16

Step-by-step explanation:

Givens

L = L

W = 1/2 L + 4

Perimeter = 56

Formula

2L + 2W = Perimeter

Solution

Sustitute

2L + 2(1/2L + 4) = 56

2L + L + 8 = 56

3L + 8 = 56

3L + 8 - 8 = 56 - 8

3L = 48

3L/3 = 48/3

L = 16

W = 1/2 L + 4

W = 8 + 4

W = 12

Check

2L + 2W = 56

2*16 + 2*12 = 56

32 + 24 = 56

56 = 56 and it checks.

Find the product.<br><br> 8y^3(-3y^2)<br><br> __ Y----
ivanzaharov [21]

Answer:

y= 12

Step-by-step explanation:

8y x 3(-3y x 2)

By multiplying 3 inside the bracket values

= 8y x -9y x 6

By multiplying the same polynomials co-coefficients

= -72y x 6

y x 6 =72

By Shifting the negative term to the other side

y = 72/6

By dividing

y= 12
