First, distribute to simplify the equation.
-3*w = -3w
-3*4 = -12
-3w + (-12) = -18
Now, isolate the variable.
-3w + -12 = -18
+12 +12
- 18 + 12 --> -6
-3w = -6
-3w/-3 = -6/-3 >>>>> w = 2
Answer: w = 2
* parenthesis tell you to multiply whatever is outside them by whatever is inside them, so let’s do that!
All we need is a calculator !!
1. 0.3(p) - 0.3(3)
0.3p - 0.9
2. 1.2(0.3x) - 1.2(1.4)
0.36x - 1.68
3. -3(2x) - 3(5)
-6x - 15
4. -7(2k) - 7(-h)
-14k + 7h
5. -1/2(6x) - 1/2( -1/3)
-3x + 1/6
6. -3(0.2m) - 3(5)
-0.6m - 15
7. -0.6(0.4y) - 0.6(-1)
-.24y + 0.6
* remember that when you multiply to negatives, it equals a positive!!
Hope I helped :)

Answer:
1) BQ ←→ CV
2) <R ←→ <N
3) KR ←→ PN
4) <Q ←→ <V
Step-by-step explanation:
Trapezoid KRBQ ∼ trapezoid PNCV, then, the corresponding parts are:
1) <K with <P
2) <R with <N
3) <B with <C
4) <Q with <V
5) KR with PN
6) RB with NC
7) BQ with CV
8) KB with PV
I honestly believe its D but I'm not for sure. Sorry if i didn't help much
