Answer:
C, y = 1.2x
Step-by-step explanation:
Notice that x, representing time, is multiplied by 1.2 each time to get y, representing the number of problems. You can find this out by dividing y by x. 36/30 = 1.2.
48/40 = 1.2.
And so on...
P.S.: If you ever come across a problem like this, subtract one y value by another y value, then subtract the corresponding x values from eachother, then make both numbers into one fraction with y as the numerator and x as the denominator. In this problem, that would look like this:
48 and 36 are both y values: 48 - 36 = 12
40 and 30 are the corresponding x values: 40 - 30 = 10
We get 12/10, which can be simplified to 1.2. The slope is 1.2.
This method will always work for a straight line and will be taught to you soon if you haven't learned it already.

The coefficient is 12a because it has a variable (a).
Answer:
TAS = 43.99 m²
Step-by-step explanation:
- TSA = total surface area
- Area of a trapezoid = (1/2)(a + b)h
(where a and b are the parallel sides and h is the height) - Area of a rectangle = width x length
This prism is made up of 4 rectangles and 2 congruent trapezoids.
Area of trapezoid = (1/2) x (1.4 + 2.3) x 1.9 = 3.515 m²
⇒ area of 2 trapezoids = 3.515 x 2 = 7.03 m²
Area of base rectangle = 2.3 x 4.8 = 11.04 m²
Area of top rectangle = 1.4 x 4.8 = 6.72 m²
Area of back rectangle = 1.9 x 4.8 = 9.12 m²
Area of sloped rectangle = 2.1 x 4.8 = 10.08 m²
Total surface area = 7.03 + 11.04 + 6.72 + 9.12 + 10.08 = 43.99 m²
