Answer:

3 * (x+4)

Step-by-step explanation:

It says three times the sum of a number and 4.

We can express the number we don't know with an x. So the phrase is saying that we have the sum of a number and 4 which is the same as writing:

x+4

Also, it says three times this sum; so we know that the sum is being multiplied by 3:

3 * (x+4)

If we read this it will be the same as the phrase "three times the sum of a number and 4)

A warehouse is 55 yards long, 35 yards wide, and 5 yards high. What is the area of the warehouse floor? If the warehouse is fill
amid [387]

Answer:

The area of the warehouse floor is 1925yd²

The volume of the boxes is 4812.5yd³

Step-by-step explanation:

First we have to calculate the area, for this we must multiply the length by the width

a = area

l = long = 55yd

w = width = 35yd

a = l * w

a = 55yd * 35yd

a = 1925yd²

to calculate the volume we have to multiply the area by the height

asks us for the volume for half the height so we have to divide the height by 2

a = area = 1925yd²

h = height = 5yd/2 = 2.5yd

v = volume

v = a * h

v = 1925yd² * 2.5yd

v = 4812.5yd³

The area of the warehouse floor is 1925yd²

The volume of the boxes is 4812.5yd³
