Answer:
![\frac{(2x-3)(x+7)}{x+3}](https://tex.z-dn.net/?f=%5Cfrac%7B%282x-3%29%28x%2B7%29%7D%7Bx%2B3%7D)
Step-by-step explanation:
Given
![\frac{2x^3+11x^2-21x}{x^2+3x}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E3%2B11x%5E2-21x%7D%7Bx%5E2%2B3x%7D)

Hence, the equivalent expression is:
![\frac{(2x-3)(x+7)}{x+3}](https://tex.z-dn.net/?f=%5Cfrac%7B%282x-3%29%28x%2B7%29%7D%7Bx%2B3%7D)
Ur answer is : h(d) = 2d + 3
because if u sub in the points in ur table, this equation works....with the number of months being d and the length of the hair being h(d)
Answer:
mean = 2
median = 2.5
Step-by-step explanation:
There are a total of 20 goals (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)
There are 10 games, so 20/10 = 2 = mean
Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5. So the median is 2.5
