Answer:
1 is x=53
2 is x=37
3 is x=45
4 is x=180
5 is x=130
6 is x=90
7 is x=15
8 is x=60
9 is x=20
10 is x=140
11 is x=47
12 is x=18
Step-by-step explanation: These can all be solved using vertical angles, complimentary angle theorem, and supplementary angle theorem! Really fancy names to say that opposite angles are equal, vertical angles (like #5). Two angles that add up to 180 degrees forming a straight line, complimentary angles (like in #1). And in a right angle two angles will always add up to 90 degrees (#7 for example). 10 11 and 12 require you to use vertical angles and complimentary angles to solve them.
(−12a^3b)(7ac+2b^2)
Step-by-step explanation:
(−24a^3(b^3)−84a^4bc
−84a^4bc−24a^3b^3=
(−12a^3b)(7ac+2b^2)
Answer:
<h3>
3 : 1</h3>
Step-by-step explanation:
B: 3m-5
Because 3 times m equals to 3m, 3 times -3 equals -9, then we have 3m-9+4, 3m-5 because -9+4=-5
