Simplify the following

-(3z)2

Uisng the PEMDAS method of simplifying arithmetic expressions, the expression would be 9z²

Given the expression :

This can be written as :

-3z × - 3z

Negative values will cancel out,

= 9z²

Therefore, the simplified form of the expression would be 9z²

Step-by-step explanation:

-(3x)²

In PEMDAS, we solve the exponent first then multiply.

-(3x)²

-(9x²)

-9x²

Best of Luck!

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
