Can someone please help it’s urgent :( ?

76

Step-by-step explanation:

5x+16 and 9x-32

first we take away 5x from both sides

16=4x-32

Then we add 32

it then becomes

48=4x or 4x=48

We divide 48 by 4 and get 12

To check your answer we plug x back in

5(12)+16=9(12)-32

5(12)+16=76

9(12)-32=76

so x is correct and since this is a square all sides are congruent

So all sides are 76

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!
