Answer: the answer is 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.
Step-by-step explanation:
Answer:
t = 2.25
Step-by-step explanation:
To find t, divide each side by 4.
9 = 4t
Divide 9 by 4:
2.25 = t
So, t = 2.25
Answer:
14
Step-by-step explanation:
perimeter = sum of all sides
so 75- (15+10+27+9)
= 75- 61
= 14
Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589

Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
