Answer:
I think the answer would be 22.15 but I'm not really sure.
The area of a rectangle is given by the product of its dimensions.
If this rectangle has a length of 2x + 7 and a width of x + 4, its area is:
The perimeter is the sum of all side lengths, so we have:
Let the width be x, it length is 2x - 4
Area = length x width
x(2x - 4) = 170
2x^2 - 4x - 170 = 0
x^2 - 2x - 85 = 0
x = 10.27
Therefore, the width ≈ 10.27 ft and the length is 2(10.27) - 4 ≈ 16.54
Answer: 33.6 min
Step-by-step explanation:
Volume = L*W*H = 9 * 13 * 14 = 1638 in^3
Vol2 = 21 * 25 *35 = 18375 in^3
18375/1638 = 11.2 times bigger, so 3min * 11.2 = 33.6 minutes
A: His texting speed after one month of practice would be 2 1/2 characters per second. (2 + 1/2)
B: His texting speed after two months of practice would be 3 characters per second. (2 1/2 + 1/2)
C: His texting speed after three months of practice would be 3 1/2 characters per second. 3 + 1/2)
D: Algebraic Expression: s = 1/2m + 2
