A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B) .5*height^2 -3.5*height = 60
B) .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60
With one cup of sugar, you need five cups of water. For one cup, you divide one by five, which would be 1/5 cups of sugar.
What is the question you have?
Answer:
61
Step-by-step explanation:
Use PEMDAS (Parenthesis first, Exponents second, Division/Multiplication third, Addition/Subtraction last)
(9+2) x 6 - 5
11 x 6 - 5
66 - 5
61
Answer: Add like terms
Step-by-step explanation:
