You divide 16 into 12 and get 1.3 repeating
many more miles of road are left to build .
<u>Step-by-step explanation:</u>
Here we have , A construction crew must build 4 miles of road in one week. On Monday, they build 1/2 mile of road. On Tuesday, they build 1/3 mile of road. We need to find that How many more miles of road are left to build . Let's find out:
- On Monday, they build 1/2 mile of road.
- On Tuesday, they build 1/3 mile of road.
Let Miles of road left to build is x So,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore,
many more miles of road are left to build .
Answer:
C
Step-by-step explanation:
First we will compute the h+k and then multiply the result by 2.
To add polynomials, we add terms whose variables are alike, for example:
we add the coefficients of x^2 together, the coefficients of x together and so on.
Therefore:
h + k = x^2 + 1 + x - 2 = x^2+x-1
Now, we will multiply this answer by 2 to get the final answer:
2(h+k) = 2(x^2+x-1) = 2x^2 + 2x -2
