Answer:
133
Step-by-step explanation:
2(_9)^2=162
3(-9)=-27
2(-9)^2 +3(-9)-2= 162-27-2=133
The answer to that question will be A
What is your question?????
Answer:
A=80
B=31
C=64
Step-by-step explanation:
A, 69, and b will equal 180 since it forms a straight line
A+69+b=180
to solve for A we subtract 53+47 from 180 and get 80
80+69+b=180
to get B we subtract 80+69 from 180 and get 31
to get c we add 85+b and subtract it from 180 getting c=64
See the attached figure to better understand the problem
we know that
[volume larger figure]=8*8*3----------> 192 units³
[volume smaller figure]=4*5*2.9----------> 58 units³
[volume of the composite figure]=192+58----------> 250 units³
