To solve this, you must rearrange the variables in the given equation. Since we are looking for h, we want the equation to be h = something. You must divide both sides by 1/3 lw. When dividing like this, you must use the KCF (Keep, Change, Flip) method. Keep the first part (v), change the sign from division to multiplication, and flip the fraction. This means that the fraction becomes 3/1 lw. When that is multiplied by v, it makes the equation h = 3v/lw. That is your final answer -> h = 3v/lw.
Answer:
.
Step-by-step explanation:
(5x^2 + 2y^2) * (3x^2 - 7y^2)
= 15x^4 + 6x^2y^2 - 35x^2y^2 - 14y^4
= 15x^4 - 29x^2y^2 - 14y^4
=

Answer:
D
Step-by-step explanation:
Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
