Question

My answer is A
Which of the following is the solution to the equation 25(z + 4) = 125 ? (3 points)
Answer

z = 5.5

z = 3.5

z = -2.5

z = -0.5

Answer 1

Are you sure you have the correct problem and solution choices?

Answer 2

\[25^{z+4}=125\]
\[5^{2(z+4)}=5^3\]
\[2z+8=3\] solve for \(z\)

Answer 3

yes, i'm sure

Answer 4

so it is not A, you have to solve
\[2z+8=3\]\[2z=-5\]\[z=-\frac{5}{2}=-2.5\]

Answer 5

the gimmick is to rewrite so both sides have the same base

Answer 6

ohhh.... i see what youre doing...i was way offf!!! ooops

Answer 7

thank you. this helps loads

Answer 8

I see from satelite that z + 4 is an exponent. Now the solution choices make sense.

Answer 9

on the left you have \(25=5^2\) and on the right you have \(125=5^3\)

Answer 10

You meant 25^(z + 4) = 125
