Answer:
6. 4.8m
7. a. 48 b. 31.4 c. 170
Step-by-step explanation:
6. 4.5^2 x 1.6^2 = c^2
22.81 = c^2
square root of 22.81 = 4.8
7.
a. 12^2 x 16^2 = c^2
400 = c^2
square root of 400 is 20, 20 + 12 + 16 = 48
b. 9^2 x b^2 = 13^2
88 = b^2
square root of 88 is 9.4, 9.4 + 9 + 13 = 31.4
c. 25^2 x b^2 = 65^2
3600 = c^2
square root of 3600 is 60, 60 + 60 + 25 + 25 = 170

Percent change = (new number - old number)/(old number) * 100
A positive percent change is a percent increase.
A negative percent change is a percent decrease.
In this problem, we have:
The new number is 15 laps.
The old number is 12 laps.
percent change = (15 - 12)/(12) * 100
percent change = 3/12 * 100
percent change = 25
Since the percent change is positive, +25, it is a percent increase.
Answer: The percent increase is 25%
Answer:
zero product property so Angela
Step-by-step explanation:
(Angela)
3x² + 10x = 0
x(3x + 10) = 0
x = 0 => x₁ = 0
3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3
Good luck !
