Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.
We can use the FOIL method.
(3b - 5c)(3x + 5y)
6bx + 15by - 10cx - 25cy
There are no like terms, so that expression is our final answer.
Answer:
Hyperbola.
Step-by-step explanation:
We start from the function:

We may get the traces if we cut the surface in planes x=k. This is equivalent to replace x for k:

The last equation is the equation of an hyperbola, which varies its characteristics depending on K (the plane cut).
Answer:
x=0 is your answer
Step-by-step explanation:
(6 + 8) + x = 14
14+x=14
x=14-14
x=0
Answer:
37 inch
Step-by-step explanation:
Area of ∆ = ½ height x base
210 = ½ x 35 x base
12 = base
Using Pythagoras theorem,
=> hypotenuse = √height² + base²
=> hypotenuse = √35² + 12² = 37
