It's "Subtraction property of equality"
It's correct
Answer:
8q+32r
Step-by-step explanation:
9 - 6 = 3
so 3 + 6 = 9 which is an addition equation that helps you find the answer.
<span>The formula for the volume of a box is:
Volume = L*W*H
We know that the length is 10 cm.
We know that the width is twice the height, so W = 2H.
Then our volume equation is:
Volume = 10*2H*H
Volume = 20*H^2
Since H^2 is in the equation, this is a quadratic equation.</span>
