Answer:
Option A)
Step-by-step explanation:
Remember that the volume of a rectangle is:
Where l is the length, w is the width and h is the height.
In the figure, these three dimensions are given as a function of the variable v.
Then the volume will be the product of the three expressions.
If we have the volume, the width and the length of the rectangle, then we find the height when we divide the volume by the product of the width and the length
The volume is:
The product of the width and the length is:
Now
we factor quadratic expressions
We use the quadratic formula to factor the expression
We also factor the quadratic function using the quadratic formula
So the height is
<span>A number multiplied by 33 makes 264. Let the number be represented by T:
</span>
T x 33 = 264
33T = 264
T = 264 ÷ 3
T = 88

Answer: 88

This kind of hard to explain without an example, so I'll do my best...
All you have to do is isolate a variable on one side of the equals sign without a coefficient. Ex: x=2y+3 The x is all alone and ready to go into the second equation.
Substitute into the second equation. Ex: 2x+5=3 Substitute: 2(2y+3)+5=3
I hope this helps!
