Answer:
2
Step-by-step explanation:
y = 0 at the point where the function intersects x-axis. Thus, yiou have to put
2x2 + x - 10 = 0
and solve the equation. It is better to factor the quadratic expression, which gives us
2x2 + x - 10 = (2x+5)(x-2) = 0
We have 2x +5 = 0 and x-2 = 0. Thus, the intercepts are x = -5/2 = - 2.5 and x = 2.

Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
The left term is (5x)³.
The right term is 10³.
So, you can use the formula for the factorization of the difference of cubes.
... a³ - b³ = (a-b)(a² +ab +b²)
Here, you have a=5x, b=10, so the factorization is
... 125x³ -1000 = (5x-10)(25x² +50x +100)
