Answer:
D. 5y^2 - 4y - 1
Step-by-step explanation:
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
Answer:
-2/3y - 2/3x
Step-by-step explanation:
Just distribute and multiply the equation
Driving 350 miles requires
(350 mi) / (10.4 mi/L) ≈ 33.65 L
of petrol.
This amount of petrol would cost
(33.65 L) × (£1.29/L) ≈ £43.41
I agree with the other persons answer.
The answer is 27.533333333..
