(3X^3 + 9X^6)(-12x^6 - 18X^5 - 6X^4)
Answer: x = 9
Step-by-step explanation:
1) Combine multiplied terms into a single fraction
2) Find a common denominator
3) Combine fractions with common denominator
4) Multiply from left to right (PEMDAS)
5) Multiply all terms by the same value to eliminate fraction denominators
6) Cancel multiplied terms that are in the denominator
7) Multiply again
8) Add _ to both sides
9) Divide both sides by the same factor getting 125x/125 = 1125/125
10) Simplify, x = 9
4x2=8 8+-12=-4 gt=-4 they are equal. Is that what you mean?
The answer is B) <span>(60 - 4x)(50 + 2x) = 2,800
The revenue without any change in price is:
$60/student x 50 students = 3,000
Every price drop reduces the price/student by four, so the first term, which describes the fee per student, is 60 - 4x
Every price drop also increases the number of students by two, so the second term, which describes the number of students, is 50 + 2x</span>
