Select all correct factored forms for the equation x^2+x−42=0 . answer choices a .(x−7)(x+6)=0 b. (x+7)(x−6)=0 c. (x−6)(x+7)=0 d. (x+6)(x−7)=0

Both B and C will give you the correct factorization for this equation.

When you factor a quadratic, you are looking for factors of the last number (-42) that add up to the middle coefficient (1). Below are the factors of -42.

1*-42

-1*42

2*-21

-2*21

3*-14

-3*14

6*-7

-6*7

And since these two are the only ones that add up to 1, we use these in parenthesis, creating the following (x - 6)(x + 7) - which is answer C. You also can switch the order due to the laws of multiplication. If you switch them around you get (x + 7)(x - 6) - which is answer B as well.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
