Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the
numbers is -99.
Which equation can be used to find m, the midpoint of the
two numbers?
Om - 5)(m + 5) = 99
O (m-10)(m + 10) = 99
O m2 - 25 = -99
O m2 - 100 = -99

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
