2m = 12
Divide each side by 2
2m/2 = 12/2
m = 6

Answer:
-2x^3 + 1/7x - 1
Step-by-step explanation:
Answer:
-2x*3+x/7-1
Step-by-step explanation:
In standard form for polynomials, you would put the monomial with the highest degree in the front first, then the second most, and so on. -2x*3 has a cubic degree, so it will come first. x/7 has a constant degree, so it will come next. Finally, -1 has no degree, so it will come last.

HELP ME PLS I WILL GIVE BRANINEST
Answers
Answer:
Angle A = 180
Step-by-step explanation:
180=7x+40
Subtract 40 from both sides
140 = 7x
Divide 7 from both sides
20=x
Substitue 20 in for x
7(20)+40
140+40 = 180
Answer:
x = 18
< A = 166
Step-by-step explanation:
Angles A and B are corresponding angles, therefore they have the same measure. Using this information, you get the following equation:
7x + 40 = 3x + 112
-3x - 3x
4x + 40 = 112
- 40 - 40
4x = 72
Divide both sides by 4.
x = 18
Solve for A:
7(18) + 40 = 166
