v=3x²
Answer:
42
Step-by-step explanation:
It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:
7a2-3ac+d2
7(2)(2) - 3(2)(-3) + (-2)(2)
28 + 18 - 4 = 42
96 degrees is your answer
supplementary means the angles add up to be 180 degrees. if 1 angle is 84 degrees then 180-84=96
Upwards from 1 to 2 is your Answer (see attachments)
