Which equation has no solution? A. 9.r +9 = 11.1 - 2 + 9
B. 7x + 30 = 3 + 6(+ 5)
C. -52 +9= 22 + 9 - 7
D. 7. – 6 = 1 + 6 (x + 5)

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!

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
