Answer:
C. x=3
Step-by-step explanation:
Because the sides are proportionate to each other
Side 3 is 3x the length of Side 1
Therefore,
Side 9 is also 3x the length of side X
3x=9
Divide both by 3
and X will be 3.
The scientific notation of this number would be 81500000e-1
Check the picture below.
so, the height of the cylinder, will be a dimension of the square, and its radius, is also a dimension of the square, since the square is being rotated about to make it.
Answer:121
Step-by-step explanation:
So we have
y=-2x-6
y=x+9
elimination
multiply second by e
2y=2x+18
just add them
y=-2x-6
<u>2y=2x+18 +
</u>3y=0x+12
3y=12
divide by 3
y=4
subsitue
4=x+9
subtract 9
-5=x
x=-5
y=4
