**Answer:**

2 was added to each side

**Step-by-step explanation:**

Given that a rectangle when changed sides, the area became 60 greater than the original

The equation given is

From the above equation we can see that the original area was

and it changed to

Original rectangle dimensions= factors of area terms = x , x+8

New rectangle dimensions = factors of

=x+2, x+10

Thus we have both length and width increased by 2 units.

The answer is 10 was added to each side.

x² + 8x + 60 = x² + 12x + 20

____

Subtract x² from both sides:

x² + 8x + 60 - x² = x² + 12x + 20 - x²

8x + 60 = 12x + 20

60 - 20 = 12x - 8x

40 = 4x

x = 40/4

x = 10

So, 10 was added to each side.

x² + 8x + 60 = x² + 12x + 20

____

Subtract x² from both sides:

x² + 8x + 60 - x² = x² + 12x + 20 - x²

8x + 60 = 12x + 20

60 - 20 = 12x - 8x

40 = 4x

x = 40/4

x = 10

So, 10 was added to each side.

Since they are similar, and a side of 10 = a side of 4, the ratio would be 2.5 : 1. You would do 6 * 2.5, which would equal 15, and (15 + 2) / 2 = 8.5 or 17/2

QUESTION POSTED AT 22/02/2020 - 03:33 PM

**Answer:**

2.2 pounds of tomatoes are bought

**Step-by-step explanation:**

Total amount spent = $5.27

Amount spent on buying pineapple = $3.40

Amount spent on buying tomatoes = total amount - amount of pineapple

= 5.27 - 3.40 = 1.87

Let x be the number of pounds of tomatoes bought

1 pound of tomato = $0.85

x pounds of tomato= 0.85x

0.85x = 1.87

Divide both sides by 0.85

x= 2.2

2.2 pounds of tomatoes are bought

QUESTION POSTED AT 22/02/2020 - 03:18 PM

Group together the terms that have "like" variables or constants in them. The first 2 terms both have an x, but the second 2 don't, so the first two are grouped together. The second 2 terms, while they do not have a common variable, both have the number 2. So those are grouped together.

(xa - xb) - (2a + 2b)--> x(a-b) - 2(a-b). Now you can actually factor out the like term (a-b) to get this: (a-b)(x-2).

(xa - xb) - (2a + 2b)--> x(a-b) - 2(a-b). Now you can actually factor out the like term (a-b) to get this: (a-b)(x-2).

**Answer:**

**Option D is correct**

**Step-by-step explanation:**

**Using point slope form:**

The equation of line is given by:

.....[1] where m, is the slope and is the point on the line

**As per the statement:**

Alejandra correctly wrote the equation y – 3 = (x – 10) to represent a line that her teacher sketched.

The line passes through the point i.,e (10, 3)

**Since, the teacher then changed the line so it had a slope of 2, but still went through the same point.**

⇒ slope(m) = 2

Substitute these in [1] we have;

**Therefore, an equation should Alejandra write to represent the new line is, **

Divide the APR by 360 days and multiply it by 30 days to get the monthly interest. Each loan is usually secured by the car you bought. So we will use the secured APR.

8. Average rating secured apr: 5.85% divide by 360 multiply by 30: 0.4875% monthly rate

Cost of car: 19,725 ; sales tax: 4.75% ; down payment: 2,175

19,725 x 1.0475 = 20,661.94 - 2,175 = 18,486.94 loan amount

18,486.94 x 0.4875% = 90.12 accrued interest for the 1st month.

9. Excellent rating secured apr: 4.80% divide by 360 multiply by 30: 0.40% monthly rate

Cost of car: 15,867 ; sales tax: 5.25% ; down payment: 10% of total cost

15,867 x 1.0525 = 16,700.02 x 90% = 15,030.02 the principal balance at the start of the loan.

10. Fair rating secured apr: 7% divide by 360 multiply by 30: 0.5833% monthly rate

Cost of new car: 19,072 ; sales tax: 4.5% ; down payment: 1,200

Cost of used car: 15,365; sales tax: 4.5% ; down payment: 1,200

19,072 x 1.045 = 19,930.24 - 1,200 = 18,730.24

18,730.24 x 0.5833% = 109.25 accrued interest

15,365 x 1.045 = 16,056.43 - 1,200 = 14,856.43

14,856.43 x 0.5833% = 86.66 accrued interest

109.25 - 86.66 = 22.59 is the difference in interest accrued by the end of the first month.
