# Which equation can be used to find the perimeter of a regular octagon with sides of length 12 m? A. P = 8 + 12 B. P = 8(12) C. P = 12 ÷ 8 D. P = 2(8) + 2(12)

QUESTION POSTED AT 18/01/2020 - 07:14 AM

The basic definition of a perimeter is the boundary line of an object. For shapes and figures, this is basically the sum of the outermost sides that define the object. Since an octagon has eight sides, with each side measuring 12m, the perimeter can be obtained by multiplying 12 m by 8 sides, or in equation form:

P = 8(12)

Among the choices, this is letter B.

P = 8(12)

Among the choices, this is letter B.

Did your explanation include the following?

Some polynomial equations have complex solutions.

Therefore, complex solutions cannot be found by graphing the related system or function in the Cartesian (x-y) plane.

Polynomial functions with all complex solutions do not have x-intercepts, and the related system of equations will not intersect.

The answer to this question would be:

Jim =6 years

Harry =2 years

To answer this question, you need to translate the description into a mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J

2. (J+2)= 2(H+2)

J+2= 2H+4

J= 2H +2

If you put the 1st and 2nd equation together, the result would be:

H+4= J

H+4= (2H +2)

H-2H= 2-4

-H= -2

H=2

After that insert the H value to either 1st or 2nd equation.

H+4= J

2+4=J

J= 6

Jim =6 years

Harry =2 years

**Answer:**

**Required Equations are x + y = 24 & x - y = 6**

**Step-by-step explanation:**

let x be the no of yellow marbles that Charles has.

and y be the no of blue marbles that Charles has.

Total Marbles that Charles has = 24

**⇒ x + y = 24 ..............(1)**

Charles has 6 more yellow marbles than blue marbles.

**⇒ x = y + 6**

** x - y = 6 ......................(2)**

Therefore, **Required Equations are x + y = 24 & x - y = 6**

QUESTION POSTED AT 20/02/2020 - 11:07 PM

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.

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

QUESTION POSTED AT 20/02/2020 - 10:55 PM

Since the problem is 4(x+8)=44 you will first need to distribute. 4 times x equals 4x. And 4 times 8 equals 32. So that leaves you with a neat problem, 4x+32=44. Next, you must subtract 32 from both sides. You need to do this to both sides to make she that they stay even. So minus 32 on both sides leaves the equation at, 4x=12. Lastly, you must divide both sides by four to get the x alone and the answer is 3. Hope this helped.
