C cuz if it opens down a is negative and also it’s a parabola so it’s quadratic
Answer:
V = 270 cm³
Step-by-step explanation:
Remember your volume formula: V=<em>lwh</em>
So, plug in all your variables and multiply:
(6)(5)(9) = 270
And we have our final answer!
Solve your equation step-by-step.
2(x−3)−17=13−3(x+2)
Simplify both sides of the equation.
2(x−3)−17=13−3(x+2)
Simplify
2x−23=−3x+7
Add 3x to both sides.
2x−23+3x=−3x+7+3x
5x−23=7
Add 23 to both sides.
5x−23+23=7+23
5x=30
Divide both sides by 5.
5x/5 = 30/5
x=6
Answer:
28 cm
Step-by-step explanation:
volume of a rectangle: l*w*h
the first cuboid: 7*4*2= 56
56=2*1*y
56=2y
28=y
Answer: 1/108
Step-by-step explanation:
2^-2 is 1/4
3^3 is 27
1/4 / 27 = 1/108
