Answer: 52.5
Step-by-step explanation:
Square
A=b*h
6*7=42
Triangle
A=b*h/2
3*7/2=10.5
Add them
10.5+42=52.5
1)
standard form
y=-6x^4 + x^2 +x
lead coefficient
-6
degree
4
constant i think
6x^4
end behavior
falls to the left and falls to the right
2)
standard form
it would stay the same
lead coefficient
2
degree
3
constant
2x^3
end behavior
falls to the left and rises to the right

The answer is vertical angles
Answer:
True
Step-by-step explanation:
x - 4y = 11 → (1)
- 3x + 5y = 25 → (2)
Multiply (1) by 5 and (2) by 4 to eliminate the y- term
5x - 20 y = 55 → (3)
- 12x + 20y = 100 → (4)
Add (3) and (4) term by term to eliminate y
- 7x + 0 = 155
- 7x = 155 ← y- term is eliminated
