Answer:
Step-by-step explanation:
-1 up and -3 down i think
Sum of the interior angles of any triangle equal to 180 degrees thus :
60 + 70 + 8x + 2 = 180
8x + 132 = 180
Subtract both sides 132
8x + 132 - 132 = 180 - 132
8x = 48
Divide both sides by 8
8x ÷ 8 = 48 ÷ 8
<h2>x = 6 </h2>
Answer:
(2x + 3)(x + 5)
Step-by-step explanation:
2x² + 3x + 15 = 0
(2x + 3)(x + 5)
2x + 3 = 0
2x = -3
x = -3/2
x + 5 = 0
x = -5
