What is the area of the regular pentagon shown below? Round your answer to
the nearest whole number.

A. 19 sq. units

B. 11 sq. units

C. 10 sq. units

O D. 24 sq. units

C. 10 sq. units

Step-by-step explanation:

Area of a pentagon = 1/2 * apothem * perimeter

1/2*(1.62)(2.36*5)=0.81*11.8=9.558

Therefore, about 10 sq. units, or option C.

I hope this helped and have a good rest of your day!

C. 10 sq units

Step-by-step explanation:

A = (b*h)/2 Use this equation

A = (2.36*1.62)/2 Simplify

A = 3.8232/2 Divide

A = 1.9116*5 Multiply by the number of sides

A = 9.558 which is close to choice C

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
