B ) a red six , given that it’s not a black card
65 miles per hour I believe because 487.5 divided by 7.5 is 65.
Step 1. Simplify
7x^2 - 8x - 4 - 2x^2 + 3x + 5 + 5x^2 - 10x - 8
Step 2. Collect like terms
(7x^2 - 2x^2 + 5x^2) + (-8x + 3x - 10x) + (-4 + 5 - 8)
Step 3. Simplify
10x^2 - 15x - 7
Answer:
answer b
Step-by-step explanation:
lol points ig
The oposite angles must be equal and adjacent angles must be supplementary
so
D=B and A=C
and
A+D=180=A+B=B+C=C+D
so ifD=42, then
A+D=180
A+42=180
minus 42 both sides
A=138=C
angle C has to be 138 degrees
