Answer:

D) 27

Step-by-step explanation:

It's a rectangle so the opposite sides are congruent to each other.

Long Side:

6x + 6 = 42

subtract 6 from both sides:

6x = 36

divide both sides by 6:

x = 6

Short Side:

5y + 5 = 30

subtract 5 from both sides:

5y = 25

divide both sides by 5:

y = 5

The Equation:

2x + 3y

substitute in the values:

2(6) + 3(5)

do the multiplication:

12 + 15

add the values together:

Given:

The expression is

$4y^2+y-45$

To find:

The value of the given expression when y=-5.

Solution:

We have,

$4y^2+y-45$

Putting y=-5, we get

$4(-5)^2+(-5)-45$

$=4(25)-5-45$

$=100-50$

$=50$

Therefore, the value of the given expression is 50 when y=-5.
