Answer:
960 ft²
Since you are doing volume, your multiplication sentence would look like
Length * Width * Height
Now, if you multiply 10 * 8 * 12, your answer will be 960 ft²
Given:
pool length : 10 yards
pool width : 8 yards
Area = 10 yds * 8 yds = 80 yd²
(10 + 2x)(8 + 2x) = 120
10(8 + 2x) + 2x(8+2x) = 120
80 + 20x + 16x + 4x² = 120
4x² + 36x + 80 - 120 = 0
4x² + 36x - 40 = 0
4(x² + 9x - 10) = 0
4(x + 10)(x - 1) = 0
x + 10 = 0
x = -10
x - 1 = 0
x = 1
the width of the deck is 1 yard
10 because 45x3=135 205-125=70 70 divided by 7 equals 10
