N^2 + 4n = 32
solving quadratics by factoring ( the solution has brackets around it)

n^2 + 4n - 32 = 0

n^2 -4n +8n - 32=0

n(n -4) +8(n -4) =0

(n-4) (n+8) = 0

n=4

n=-8

25% is the answer

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
