Answer:
6x^2 +x -12
Step-by-step explanation:
Substitute for A and B and collect terms.
2B +3A
= 2(3x^2 -x +3) +3(x -6) . . . . substitute for A and B
= 6x^2 -2x +6 +3x -18 . . . . . eliminate parentheses
= 6x^2 +x -12 . . . . . . . . . . . . collect terms
Answer:
- The measure of ∠A is 66°.
Step-by-step explanation:
<u>We know that:</u>
- ∠A = 3x + 18
- ∠D = 4x + 2
- ∠D = ∠A
<u>Now, let's solve the equation. ∠D = ∠A.</u>
- => 3x + 18 = 4x + 2
- => -2 + 18 = x
- => 16 = x
<u>Now, let's substitute the value of x into any equation.</u>
- => 4x + 2
- => 4(16) + 2
- => <u>66°</u>
Hence, the measure of ∠A is 66°.
