Answer:
90 cm
Step-by-step explanation:
15 x 6 = 90
3x^2 + 8x - 4 - (6x^2 - 5x + 3)....distribute thru the parenthesis
3x^2 + 8x - 4 - 6x^2 + 5x - 3 .....combine like terms
-3x^2 + 13x - 7 <==
Answer:
It will cost $700 to play the entire schedule.
Step-by-step explanation:
Given : 
To Find : A softball league has 5 teams, each of which play the others twice. If the league pays $35 per game, how much will it cost to play the entire schedule?
Solution:
Equation for total no. of games when all the teams play each other twice is 
Now we are given that A softball league has 5 teams, each of which play the others twice.
So, Substitute x = 5 in the given equation


So, The total no. of games = 20
Cost for 1 game = $35
So, cost for 20 games = 
Hence it will cost $700 to play the entire schedule.
Answer:

Step-by-step explanation:
The zeros of the polynomial function are given us as -5,-1,2
If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:
f(x) = (x - α)(x - β)(x - ω)
where α = -5, β = -1, and ω = 2
