Find f(x) if it is known that f(2a−1)=7a−13

f(2a−1)=7a−13

7(2a−1) − 13

14a − 7 − 13

14a − 20

Step-by-step explanation:

replace a with f(2a − 1)

distribute the bracket

combine -7 and -13 because they are the like terms here.

quit

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
