Tabitha wants to hang a painting in a gallery. The painting and frame must have an area of 58 square feet. The painting is 7 feet wide by 8 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?

Answers

The quadratic equation would be;
x2+15x-2=0

Working:
Assuming the area around the painting i.e the frame, has a uniform thickness, then;
Length of painting and frame = 8+x
Breadth of painting and frame= 7+x

The area from above step gives;
 A= LxW
A= (8+x)(7+x)
On expanding, 56+8x+7x+x2
On simplifying,
56+15x+x2. This should be equal to 58.
58=x2+15x+56
Taking 58 to the other side,
x2+15x-2=0

a pack of toy cars contains 12 cars. if Sylvia buys only packs of 12, what are two possible numbers of cars that she could buy

Answers

Answer: 36 and 24

Step-by-step explanation:

Hi, since a pack of cars has 12 cars, if she buys only packs, the possible number of cars that she could buy will be multiples of 12.

Multiples of 12: 12,24,36,48,60,72,84,96,108,120, etc

We can pick any multiple of 12.

For example if she buys 3 packs of cars:

3 x 12 = 36 cars

If she buys 2 pack of cars:

2x12=24 cars

Feel free to ask for more if needed or if you did not understand something.

24, 36, 48 etc.. just keep adding 12
