Answer:38x-34

Step-by-step explanation:

f(x)=x^2+3x-7

g(x)=5x-3

We multiply the entire F equation times two, (x^2+3x-7)*4=

(4x^2+12x-28)

Now the entire g equation by 2, (5x-3)*2

(10x-6)

Now we add both equation

(4x^2+12x-28)+(10x-6)

(4x^2+22x-34)

(4x*4x+22x-34)

(16x+22x-34)

38x-34

Hopefully this is correct :)))

11/4 hours 19/8 hours 2.6 hours witch is closest to 2 hours?

ExtremeBDS [4]

Answer:

$\frac{19}{8}$ hours is closest to 2 hours.

Step-by-step explanation:

We have been given three numbers and we need to decide which of the three numbers is closest to 2.

In order to decide that, we will convert each of the given numbers into decimals and then we will compare.

$\frac{11}{4} =2.750\\\frac{19}{8}=2.375\\2.6=2.600$

Upon comparing 2.750, 2.375 and 2.600 we know that 2.375 is closest to 2. Therefore, out of the given three numbers, $\frac{19}{8}$ is closest to 2.
