There would be 60 questions on the test.
90%=54
1%= 54/90 = 6/10
100%= 6×100/10 =6×10=60
Answer:
1). 2x^2-3x+20
2). 4x^2-14x+6
Step-by-step explanation:
1. (x-4)(2x+5)
FOIL:
(x)(2x)+5(x)-8(x)+(4)(5)
2x^2+5x-8x+20
=2x^2-3x+20
2. (4x-2)(x-3)
FOIL:
(4x)(x)-(3)(4x)-2(x)-2(-3)
4x^2-12x-2x+6
=4x^2-14x+6
<h3>
Therefore he drives 400 miles from 9 am to 5 pm.</h3>
Step-by-step explanation:
Given someone drives 50 miles in an hour.
Time = 8 hours
So, he drives = (50×8) miles = 400 miles

Answer:
90 mph
Step-by-step explanation:
if it can go 45 mph, in 2 hrs, it should go 90
45*2=90
