For this case we have to:

Given two lines:

y_ {1} = m_ {1} x_ {1} + b_ {1}\\y_ {2} = m_ {2} x_ {2} + b_ {2}

By definition, if both lines are perpendicular to each other, then the product of their slopes is -1. That is to say:

m_ {1} * m_ {2} = - 1

ANswer:

The product of the slopes of two perpendicular lines is -1.

Expand and simplify (x+5)(x+2)
Savatey [412]
Answer= x²+7x+10

When we want to expand expressions such as this, the FOIL method helps us remember what exactly to do. FOIL stands for

F:First
O:Outer
I:Inner
L:Last

So, given the expression (x+5)(x+2), lets multiply the first two terms.

x*x=x²

now the outer two terms

x*2=2x

now the inner terms

5*x=5x

and the last terms...

5*2=10

When we combine these expressions we get:

x²+7x+10

I think this is what you meant to be answered in your question, if I have been mistaken, just comment and I'll edit my answer....

Which shapes have at least one pair of parallel sides?
elena-s [515]
Parallelograms and trapezoids always do.

(Note:  "Parallelograms" includes rectangles, squares, and rhombussesses.)

Any polygon with more than 4 sides <u>can</u> have at least one pair of parallel sides,
but it's not guaranteed.
