What is 2x-4. I really don’t understand

ddd [48]

Answer:

2 * -4 = -8

Step-by-step explanation:

2 * -4 = -8

It is just like multiplying two numbers like... 2 * 4 = 8

You must need to know that:

+a * -b = -c

-a * -b = +c

+a * +b = +c

In your question;

+a * -b = -c

a = 2

b = -4

c = -8

therefore:

2 * -4 = -8

Answer:

$h=12.5\ in$

Step-by-step explanation:

we know that

The surface area of a square prism is given by the formula

$SA=2(b^2)+4bh$

where

b is the length side of the square base

h is the height of the prism

we have

$b=5\ in\\SA=300\ in^2$

substitute

$300=2(5^2)+4(5)h$

solve for h

$300=50+20h\\20h=300-50\\20h=250\\h=12.5\ in$
