Factor to this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?).
The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6.
x - 3 = 0
x = 3
x + 2 = 0
x = -2
The two solutions are therefore, x = 3 and x = -2.
Hope it helps
Part A
Her steps were

Kelsey made a mistake on line 3. Note how the 17/6 flips to 6/17. This is not correct. You keep the first fraction the same, but you do flip the second fraction. This only applies when you divide two fractions.
The third step should look like 
=======================================================
Part B
Here's what she should have written

If you want to convert that improper fraction to a mixed number, then you could do something like this

Or you could divide 17 over 8 using long division to get 2 remainder 1. The 2 is the quotient that goes to the left of the 1/8. The remainder of 1 is the numerator of 1/8.
with it's formula
Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.
Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is
. We can rearrange that to get:
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
Answer:
35 + 37
Step-by-step explanation:
if you try any other number like: 37 + 39 = 76 that doesn't work well because its higher that 75.
