Vertical angles are equal
5x - 40 = 3x + 8
5x - 3x = 8 + 40
2x = 48
x = 48/2
x = 24
m∠ABC = 3x + 8 = 3 * 24 + 8 = 80°
(or m∠ABC = 5x - 40 = 5 * 24 - 40 = 80°)
The answer is 1
Step-by-step explanation:
look at the line going up and down
Answer:
0.21 and 0.22
Step-by-step explanation:
It’s B because 5 = -3(-3) - 4
5=9-4
Just plug in the numbers and see what works
Answer:
Step-by-step explanation:
Use FOIL method
F -> First
O Outside
I inside
L Last
(a - b)(a + 2b)= a*a + a *2b + (-b)*a + (-b)*2b
= a² + <u>2ab - ab</u> - 2b²
Combine like terms
= a² + ab - 2b²
