A is 23 and the answer to b is 77
-4b-8 + -1b^2 +2b^3
-4(-2)-8+-1(-2)^2+2(-2)^3
8-8+2^2-4^3
4-64
60
Area of a rectangle=length×width. If the area is 161 and the length is 14 then that means: 161=14×width. You would then divide 161÷14 and you will find that the width is 11.5.
Answer:
60°
Step-by-step explanation:
Complementary angles both add up to 90°. Therefore if one angle is twice the other, then if we divide 90 by 3 then we get 30. Two parts of 30 is 60 plus the other 30 and we get 90. The individual angle is 60°and the other is 30°
