The pythagorean theorem says that a² + b² = c²
You're given the b and the c so substitute the values in: a² + 12² = 15²
a² + 144 = 225; subtract 144 from both sides
a² = 81; square root each side
a = 9, or choice C
d) Aislinn's average per month on her car is 1,751 miles per month.
<h3>How to find the average speed?</h3>
The average speed is calculated by dividing the total distance traveled by the total time it took to travel that distance. Speed is the rate at which something moves at any given time.
Average speed is the average rate of speed over the course of a journey. Velocity exists as the directional speed of a moving object as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard.
Given,
After 8 months, the odometer read 14,010 miles.
Solution:
t = 8,
d = 14,010 miles,
s = ?
s = d/t
s = 14,010/8
s = 1751 miles/month.
Aislinn drove an average of 1,751 miles per month.

Answer:
x=4
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(6+x) * 6 =(5+x+3) *5
(6+x) * 6 =(x+8) *5
Distribute
36+6x = 5x+40
Subtract 5x from each side
36+6x-5x = 5x-5x+40
36+x = 40
Subtract 36 from each side
36+x-36 = 40-36
x = 4
Answer:
pi
Step-by-step explanation:
pi is always 3.14, so it is the constant here
