The equation which is supposed to help you is this one:
a^2 - b^2 = (a+b) (a-b)
So, what we need to do here is apply this equation:
k^2 - 9h^2 =
k * k - (3h)^2 =
(k + 3h) (k - 3h)
Answer:
a. {7,14}
b. {10,17,24,31}
c. (no)
Step-by-step explanation:
c. because for two different values of domain there is a single value of codomain (range )
The force on the four wheeler i think is 42N because Frankie pushes with a force of 40N and Caitlin pulls with a force of 2N that means u add the two numbers together and it becomes 42N.
A common denominator for 2/5 is 4/10 because 2/5 times the denominator and numerator by 2 is 4/10
And the common denominator for 1/2 is 5/10 because 1/2 times the denominator and numerator by 5 is 5/10
So the equivalent denominators for both fractions is 4/10 and 5/10
