Step 1: Distribute the subtraction sign to all the numbers in the second set of parentheses...
Step 2: Combine like terms ('s go with 's)
Step 3: Combine like terms ('s go with 's)
Step 4: Combine like terms (normal numbers go with normal numbers)
1 + 2

I don't really know how to explain this one but I got: (7m-6n)(7m-6n)
Y = 3.50x
245 = 3.50x
x = 245/3.5
x = 70 coffee mugs
315 = 3.50x
x = 315/3.5
x = 90 coffee mugs
Ronny needs to sell 90 coffee mugs to reach his sales goal. However, he already sold 70 coffee mugs, so he needs to sell an additional 20 coffee mugs to reach 90 coffee mugs and reach his $315 sales goal.
Quadratic in equality is quadratic function that is compared to another function like: x^2+4x-1<2x-3. the answer for x must comply to both sides.
