Check the picture below.

notice, the gift box is just 6 rectangles stacked up to each other at the edges,

top and bottom, two rectangles of 25x32

front and back, two rectangles of 25x40

so, just get the area of all 6 rectangles, add them up, and that's the "surface area" of the rectangular prism, and that's how much paper will be needed to cover it.

Choose the graph which represents the solution to the inequality. 12x + 4 ≤ -8
user100 [1]

Answer:

<h2>x\leq -1</h2>

Step-by-step explanation:

Steps:

12x+4-4\leq -8

Subtract 4 from both sides:

12x+4-4\leq -8-4

Simplify:

12x\leq \frac{-12}{12}

Divide both sides by 12:

\frac{12x}{12} \leq \frac{-12}{12}

Simplify:

x\leq -1

Daniella is interviewing for a job. She wants her take-home pay to be at least $51,000 
Lilit [14]
Okay. So Daniella wants to have a take-home pay of at least $51,000, but she ahs to pay 15% income tax, which means 15% of what she earns will be gone. To find out the least amont of salary she needs to make, we can write and solve a proportion. Set it up like this:

51,000/x = 85/100

This is because we are looking for the amount of money made overall, but the $51,000 is only part of the salary earned, and even though you pay 15% income tax, you still take home 85% of your salary. Cross multiply the valyes in order to get 5,100,000 = 85x. Divide each side by 85 to isolate the variable. 5,100,000/85 is 60,000. Let's check this by multiplying by 85% (0.85). 60,000 * 0.85 is 51,000. There. x = 60,000. Daniella will need to make at least $60,000.
