H is correct one!!
<u>By Pythagoras </u><u>theorem</u>
H² = B² + A²
H= 9
B= x
A = 3
<u>Now</u>
9² = 3² + x²
9² - 3² = x²
72 = x²
√72 = x
Answer:
Step-by-step explanation:
Step-by-step explanation:
So you solve the equation for x and then solve it for y. If the x and y match the given ordered pair then the answer is yes
If one is at a speed of 35 mph and the other 60, sum the speeds to work with just one number:
35 + 60 = 95mph
The formula for time is:
Time = Distance / Speed
Time = 855 / 95
Time = 9h (D.)
Hope it helped,
Happy homework/ study/ exam!
5x + 2 is a denominator.
A denominator cannot equal zero since division by zero is undefined.
Set the denominator equal to zero and solve for x to find which value of x makes the denominator zero.
5x + 2 = 0
5x = -2
x = -2/5
The non-permissible replacement for the variable is -2/5.
