Answer:
B. 
+ 2x³ - 8x² - 22x - 15
Step-by-step explanation:
1. (3x² - 2x - 3)(5x² + 4x +5)
+ 12x³ + 15x² - 10x³ - 8x² - 10x - 15x² - 12x - 15
2. Combine like terms
+ 2x³ - 8x² - 22x - 15
Answer:
18 and 6
Step-by-step explanation:
Rn = 6 Ratio numerator
Rd = 2 Ratio Denominator
Rs = Rn + Rd
Rs = 6 + 2
Rs = 8
Ratio Sum
a = 24 Amount to Divide
M = a ÷ Rs
M = 24 ÷ 8
M = 3 Multiplier Ratio Division Calculation
Rr = Rn × M : Rd × M
Rr = 6 × 3 : 2 × 3
Rr = 18 : 6
Answer
Substitute w by 7
7^3
7x7x7 =343
The expected enrolment in 7 years is 1845.

The formula for calculating future value of the number of students is an exponential equation with this form:
FV = P (1 + r) ^n
- FV = Future population
- P = Present population
- R = rate of growth of the population
- N = number of years
1500 x (1.03)^7 = 1845
