Cubes have 6 faces, so to find the answer, you can find the area of one face and multiply it by 6. The area of one face would be 4 × 4 = 16 cm², so then 16 × 6 = 96 cm², which is your answer.

I hope this helps!

H(x) =-4x+ 3; Find h(x-1)

Mila [183]

Answer:

h(x-1) = - 4x + 7

Explanation:

To find h(x - 1), we need to replace x by (x-1) on h(x). Then:

$\begin{gathered} h(x)=-4x+3 \\ h(x-1)=-4(x-1)+3 \\ h(x-1)=-4x-4(1)+3 \\ h(x-1)=-4x+4+3 \\ h(x-1)=-4x+7 \end{gathered}$

Therefore, h(x-1) = - 4x + 7

A car used 11 1/2 gal of gasoline on a 345-mile trip. How many miles can this car travel on 1 gal of gasoline? ____mi

lyudmila [28]

Answer:

The answer to your question is: 30 miles can the car travel.

Step-by-step explanation:

Data

gasoline used = 11 1/2 gal

distance = 345 mile-trip

distance travel with 1 gal = ?

Process

Convert 11 1/2 to a improper fraction 11 1/2 = 23/2

Rule of three

23/2 gal ----------------------- 345 miles

1 gal ---------------------- x

x = (1 x 345) / 23/2

x = 345 / 23/2

x = 690/ 23

x = 30 miles
