15.6 cm
8.8 cm
x = [ ? ]cm

x≈4.1

Step-by-step explanation:

15.6/2=7.8

Use Pythagorean Theorem

7.8^2+x^2=8.8^2

60.84+x^2=77.44

x^2=16.6

x=√16.6≈4.1

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

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!
