Answer:
x=12
Step-by-step explanation:
Since the triangle is isosceles, the 2 base angles are congruent.
Also, the interior angles of a triangle add up to 180.
32+7x-10+7x-10=180.
Solve.
14x+32-20=180
14x+12=180
14x=168
<u>x=12</u>
This would be subtracting! hope this helped! :)
Take out the GCF of -4d, which creates
-4d(d^2+7d-1)
Doesn't seem right... tell me if I messed up anybody... if not, there's your answer.
Answer:
the answer is k=-4 hope this helps
