Answer:

the size of the box is 45"

Step-by-step explanation:

screen measures 36 inches wide by 27 inches high

The diagonal of the box is the size you see on the box.

Lets find the diagonal of the box using  pythagorean theorem

c^2= a^2 + b^2

Where 'a' is the length and 'b' is the width

c^2= 27^2 + 36^2

c^2= 729+1296=2025

Now take square root on both sides

c=45

So the size of the box is 45"

Expand and simplify 4(2x +7) – 3(x + 5)
Vikentia [17]

Answer:

4\left(2x+7\right)-3\left(x+5\right)=5x+13

Step-by-step explanation:

Given the expression

4\left(2x+7\right)-3\left(x+5\right)

<u>Expand and simplify the expression</u>

4\left(2x+7\right)-3\left(x+5\right)

Expand  4(2x + 7) = 8x + 28                  

4\left(2x+7\right)-3\left(x+5\right)=8x+28-3\left(x+5\right)

Expand  -3(x + 5) = -3x - 15

                                 =8x+28-3x-15

Group like terms

                                  =8x-3x+28-15

Add similar elements:  8x - 3x = 5x

                                   =5x+28-15

Simplify

                                    =5x+13

Therefore, we conclude that:

4\left(2x+7\right)-3\left(x+5\right)=5x+13
