Answer:
15 years
Step-by-step explanation:
$10,312.50-$7500 = $2,812.50 in interest we need over time
7500 x 2.5= $187.50/year (interest)
$2,812.50 / $187.50 = 15 years
56.52 ÷ pi(3.14) = 18
18 ÷ 2 =9
A = pi(3.14)r^2
A = 3.14 × 9^2
A = 3.14 × 81
A = 254.34in^2
Answer: = x² - 12x + 35
(x - 5)(x - 7)
= x² - 5x -7x + 35
= x² - 12x + 35
Step-by-step explanation:
Answer:
Step 2.
Step-by-step explanation:
When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:
3(x+8)² = 75
Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:
(x+8)² = 25.
Therefore, his mistake was made at Step 2.
