Answer:
10s²-6s+9
Step-by-step explanation:
C = -3 + 5s²
B = -2s + 5
2(-3 + 5s²) = -6 + 10s²
3(-2s + 5) = -6s + 15
10s² - 6s + 9

-6x = 42
x = -7

Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92
The question is incomplete. The complete question is :
Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below. What is the total number of cubes that Georgia needs to exactly cover the bottom of the box with a layer one cube deep?
Solution :
It is given that :
There are small cubes that has a dimension of 4 in x 4 in x 4 in.
There is also a box which has a dimension of 24 in x 20 in x 12 in.
We need to find out how many small cubes will Georgia need to cover the bottom of the box.
So, we need to find out the surface area of the one cube and the box.
Therefore, the surface area of one cube = side x side
= 4 inch x 4 inch
= 16 square inches
Similarly the area of the box can be find by = length x breath
= 24 in x 20 in
= 480 square inches
Therefore, dividing the area of the box by the area of the cube, we get

= 30
So Georgia will require exactly 30 cubes to cover the bottom of the box with a layer of one cube deep.
Answer:
$318.79
Step-by-step explanation:
To do this problem, to find the real end amount paid, you must add up all the prices and add the sales tax. To do this, you add them to 296.55, and multiply it by the decimal form of the sales tax added to 1, so 1.075 which is 318.791 rounded to 318.79
