Answer:
Hope that answers your question
2+4a=-10
First, subtract 2 from both sides.
4a=-12
Then divide 4 from both sides.
a=-3
hope it helps!
Work done on cart
:

Explanation:
Work done
W
is defined as the product of force
F
and distance
s
:
⇒
W
=
F
⋅

Let's substitute the values of
F
and
s
into the equation:
⇒
W

Answer:
The car dealer must sell 105 cars in May to reach his goal.
Step-by-step explanation:
Given that the car dealer sold 84 cars in April, and wants to increase his May sales by 25%, to determine the number of cars he must sell to reach his goal it is necessary to perform the following calculation:
84 + (84 x 0.25) = X
84 + 21 = X
105 = X
Therefore, the car dealer must sell 105 cars in May to reach his goal.
