Answer:

x = 26

Step-by-step explanation:

Before we begin, we must first remember that to solve for x, we have to get the variable (x) by itself.

To start, you would first subtract 12 from the left and right side of the equation.

3x + 12 - (12) = 90 - (12)

The 12 would cancel out on the left side (12 - 12 = 0) and you would now be left with 3x = 78.

Next, you would divide the left and ride side by 3.

3x ÷ 3 = 78 ÷ 3

This gives you the answer of 1x = 26 or x = 26

Keith_Richards [23]

Answer:

  • length: 30 ft
  • width: 10 ft

Step-by-step explanation:

The description of the garden fits that of 3 squares arranged side-by-side. The area of each of those would be 100 ft², so their side length would be ...

  s = √A= √(100 ft²) = 10 ft

This dimension is the width of the garden, whose length is 3 times this amount.

The length and width of the garden are 30 ft and 10 ft, respectively.

Think of it as two rectangular prisms next to each other, and find the volume of each one separately.

The big one on the left has a volume of 4 * 12 * 6, or 288.

The smaller one on the right has a volume of 2 * 6 * 6, or 72.

288 + 72 = 360. 360 cubic feet of water are needed.
