Answer:it will the take 5 mitutes
Step-by-step explanation:
Let x represent the distance at which both companies charge the same amount.
Let y represent the cost of x miles when using company A.
Let z represent the cost of x miles when using company B.
Company A charges a flat fee of $4 plus $2 per mile. It means that
y = 4 + 2x
Company b does not charge a flat fee but charges $2.80 per mile driven. This means that
z = 2.8x
To determine the distance before both plans will be be the same, we would equate both equations. It becomes.
4 + 2x = 2.8x
2.8x - 2x = 4
0.8x = 4
x = 4/0.8 = 5
Answer:
8x²−6xy+20x−15y
Step-by-step explanation:
(4x−3y)(2x+5)
=(4x+−3y)(2x+5)
=(4x)(2x)+(4x)(5)+(−3y)(2x)+(−3y)(5)
=8x²+20x−6xy−15y
=8x²−6xy+20x−15y
35+35+35+35+35+35+35+35+35+35+35+35
