Answer:
x+20+5x+10=180
6x+30=180
6x=150
x=25
supplementary angles
Step-by-step explanation:
14/-7
$30
x =4(3.45)+1.5(3.98)+2(4.35)+1.53
=13.8+5.97+8.7+1.53
=30
2x² + 8x - 35
x(2x + 3) + 5(x - 7) ← distribute both parenthesis
= 2x² + 3x + 5x - 35 ← collect like terms
= 2x² + 8x - 35
no it actually the opinions you have
36
5x is 15
x is 3
12 times 3 is 36
