5+23= 28 .........................
4 * (25 * 1.2) = (4 * 25) * 1.2
100+4200 is 4,300
4,300+50 is 4,350 if you rounded that to the nearest 10,000 it's 10,000
Explain cause I think you're missing something from the question
Answer:
a. 
b. x ≠ -5 (Vertical asymptote) and x ≠ 5 (Hole)
Step-by-step explanation:
Factor the numerator (Grouping):
Two numbers that multiply to -30 and add to -7 = -3 and 10
![[2x^2 - 10x] + [3x - 15]](https://tex.z-dn.net/?f=%5B2x%5E2%20-%2010x%5D%20%2B%20%5B3x%20-%2015%5D)

Factor the denominator (Difference of Two Squares):
= 
Factored Expression:
(x - 5) can be factored out of top and bottom as a hole-

Variable Restrictions:
Denominator ≠ 0

Vertical asymptote at x = -5 ⇒ x ≠ -5
I think its like if you got 80% on a quiz and 20% on the exam then your grade would be 60% which is usually a F
