Answer:
5 3/4 hours
Step-by-step explanation:
They drove 3 1/2 hours then 2 1/4 hours. We need to find the total of these to find how long this part of the trip was
(3 + 1/2) + (2 + 1/4) = 5 + 1/2 + 1/4
For 1/2, we can multiply both the numerator and denominator by 2 to get
1/2 = 2/4
Substituting that in, we get
5 + 2/4 + 1/4
= 5 + 3/4 hours
This can be factored as (x-3)^2, so they are equal
Step 1.)
7x + 7 * 4.
We need to expand this term by multiplying a term and an expression.
The following product distributive property will be used:
A(B+C) = AB + AC
Numerical factors in this term have been multiplied.
In our example, the resulting expression will consist of 2 terms:
the first term is a product of 7 and x
the second term is a product of 7 and 4.
7x + (7 * 4)
Numerical factors in this term have been multiplied.
Which equals:
7x + 28
Hope you understand this and it helps. Have a great evening!
