Answer:

n = -6 or n = 4.

Step-by-step explanation:

-3 | -8n – 8 | = -120

Divide both sides by -3:

| -8n – 8 | = 40

This gives us 2 equations because the expression in the absolute signs can be positive or negative:

-8n - 8 = 40

so -8n = 48

n = -6.

and

-8n - 8 = -40

-8n = -32

n = 4.

Radius of a circular ground is 21m. Find.

trapecia [35]

The circumference of a circle of radius $r$ is

$C=2\pi r$

So, in your case, the circumference is

$C=2\cdot \pi \cdot 21 = 42\pi$

The circumference is actually the length of the "perimeter", so the answer to questions 1 and 2 looks the same actually
