4x+7 is the simplified answer
Answer:
True
Step-by-step explanation:
When a linear function is graphed, it forms a straight line.
A nonlinear function would be a curved line if graphed. Some other nonlinear functions would have a straight line and then curve.
Let's find the total cost before the tax and tip.
14+16+2*1.25+2*4.25 = $41
The tip is added before the tax so let's calculate it first.
1.15 * 41 = $47.15
Now add the 7% tax.
1.07 * 47.15 = $50.45
There are 6 faces and area of each face = 4.7^2
so surface area of the whole cube = 6 * 4.7^2 = 132.54 in^2
