Are these two quadratic expressions
equivalent? Explain.
(x+3)(x-4)
x2 + 7x - 12

I know the 1st one.

(x+3)(x-4) = x-12

Step-by-step explanation:

This is called a foil method

1st: We multiply the two first numbers - x*x = 2x

2nd: We multiply the two outside numbers - x*(-4) = -4x

3rd: We multiply the two inside numbers - 3*x = 3x

4th: We multiply the two last numbers - 3*(-4) = -12

Then we combine them - 2x-4x+3x-12

Then we simplify - x-12

Hope this helped!

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
