Answer:
a. n= 1x +7
b. n= 12 + 4x
Step-by-step explanation:
Yes... indeed it is 1/8 because
125/1000 In simplest form is 1/8
Answer:
x = -5
Step-by-step explanation:
Get x by itself on the left side. To do that, subtract the 7. Do to both sides. This makes x = -5
It's obviously none of the above because the true area will have a square root of 3 in it because of the equilateral triangle. They want us to find the approximate area. When I was in school the difference between an approximation and the exact answer was greatly stressed but that seems to be fading of late.
That's a rectangle less an equilateral triangle. The area of an equilateral triangle is
which is easily derived but I won't bother here.

Answer: b
