200,000 because 50 and down is 100,000 and 50 and up is 200,000 rounded to the nearest hundreds thousand
A. 11w=88
11w/11=88/11
w=8
b. 7u=210
7u/7=210/7
u=30
c. v÷81=9
v/81×81=9×81
v=729
d. c÷4=16
c/4×4=16×4
c=64
Answer:
(2) 6x^2+40x +50
Step-by-step explanation:
(4x+10)*(2x+5) = 8x^2 +40+50
minus 2x^2
=6x^2 +40 +50
The mechanical advantage is the ratio of the radii: 5/0.5=10.
