2x^2-5xy-y^3 if x=-3, and y=-2
2(-3)^2- 5(-3)(-2) -(-2)^3
=2(9) - 5(6) - (-8)
= 18 - 30 + 8
= -4
Answer:
42
Step-by-step explanation:
alternate exterior angles are equal. Therefore 32 = y - 10. Solving for y:
y - 10 = 32
y = 32+10
y = 42.

Answer: 400 square feet
Step-by-step explanation: One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room like a bathroom. Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room
5√7 + 12√6 - 10√7 - 5√6
Write it like this:
(12√6 - 5√6) + (5√7 - 10√7),
as the 12 and 5 are both being multiplied by √6, they can be added or subtracted and its the same with 5 and 10, so it becomes:
7√6 - 5√7
You should leave it like this.
