Answer:
The Orange circle is: 78.5 cm
And The Blue circle is 314.2 cm
Step-by-step explanation:
By taking the formula r^2(pi), and filling it in with the radius for the orange circle you will get 78.5. For the blue circle the radius would be the orange's radius combined with the rim given. Using the same formula you will get 314.2.
You count each unit square and it counts as one so for number two from point o to point a there are 5 unitsif each side we’re 5 hints and there are 6 sides you multiply five by six to get the answer of 39 for number three
The first set of parentheses is unnecessary, so just drop it.
The second set of parentheses has a negative sign to its left.
To simplify the second set of parentheses, change every sign inside the parentheses. Then combine like terms.

= - x - 2 - 4x - 3
= -x - 4x - 2 - 3
= -5x - 5

Actually those 4 angles are equal to 110 because those are vertical angles
Hello,
With
y=x²-4x-21
y=-5x-22
==>x²-4x-21=-5x-22
==>x²+x+1=0
