Answer is c) 2x - 15 because x is Valerie's grade
Allie's grade is <span>taking Valerie's grade, multiply it by 2 and subtract 15</span>
Answer:A
Step-by-step explanation:
Hello,
one of two<span> fixed points inside an ellipse from which the </span>sum<span> of the </span>distances<span> to any point on the ellipse is constant. </span>
(9+w)w=252 or w(w+9)=252.
The quadratic equation applies: w²+9w-252=0=(w+21)(w-12), so w=12, because a negative zero is meaningless.
So the dimensions are width=12 in and length=21 in.
Answer:
2π
Step-by-step explanation:
Area = πr^2
= π2^2
= 4π
4π is the area of the whole circle, so divide it in half to get the semicircle.
<u>= 2π</u>
