Answer:
9. 6k + 5 and 2k - 1.
10. 5√2 .
Step-by-step explanation:
9. Area = 12k^2 + 4k - 5
Factoring:
12k^2 - 6k + 10k - 5
= 6k(2k - 1) + 5(2k - 1)
= (6k + 5)(2k - 1)
So the required lengths are 6k + 5 and 2k - 1.
10. The ratio of a leg to the hypotenuse is 1: √2 so if the hypotenus = 10 the length of a leg is 10 / √2
= 10 √2 / 2
= 5√2 .
Answer:
Price at store B = $66.94
Step-by-step explanation:
Given:
Price of headphones at Store A = $89.25
Find:
Price at store B
Computation:
Price at store B = 3/4[Price of headphones at Store A]
Price at store B = 3/4[89.25
Price at store B = $66.94
Isolate the r. Note the equal sign. What you do to one side, you do to the other.
Divide i from both sides
e/i = ir/i
r = e/i
r = e/i is your answer
