Firstly, since these two fractions have the same denominator, add the numerators up:
While it appears that the answer is -6/4, you can further simplify it by dividing the numerator and denominator by 2:
<u>Your answer is </u>
Solve for r and then c by replacing x with 5 then subtract:
r = x^2 +5x + 14 = 5^2 +5(5) +14 = 25 +25 +14 = 64
c = x^2-4x +5 = 5^2-4(5) + 5 = 25-20 +5 = 10
r- c = 64-10 = 54
so the store will have a profit of 54,000 after it's 5th month
Answer is C
2. Combine like terms
3.subtraction property of equality
4.division property of equality
5. Reflexive property
30 km/h to the store. 60 km/h back from the store.
(60 + 30) \ 2
We use the mean average formula.
90 \ 2
Final answer: 45
I'm going to answer in statement proof form.

mANGLE(ABC) is congruent to mANGLE(ADC) Properties of a Parallelograms
3(BCD)+(BCD)=180 Supplementary Property of Parallelograms
4(BCD) = 180 Simplify
BCD=45 Division property of Equality
180-45=ABC Properties of Supplementary Angles
135=ABC Simplify
135=ADC Transitive property of equality
