A commutative
B. distributive
C associative
D. arthumetuc fact
Answer:
17x+15 is your answer, I think it is A communative
Step-by-step explanation:
The property is illustrated in step 3 would be A commutative properties of addition
What is commutative property?The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.
This property applies to multiplication also.
We are given the equation as;
5x + 1 + 12x + 4
= (5x + 1) + (12x + 4)
(5x + 12x) + (1 + 4)
Therefore, we can see that this shows the step of commutative properties of addition

Answer:
190 yd^2
Step-by-step explanation:
This is a parallelogram, and you can essentially take the dotted line, cut off the excess and stick it on the back creating a rectangle with length 15.2 yd and height 12.5. To find the area you multiply the 2 together getting 190 yards squared.
3. Find the measure of the sides of the triangle if the vertices of AEFG are E
(1,4), F(5, 4), and G(1,0). Then classify the triangle by its sides.
The triangle EFG is an isosceles triangle as side EF is congruent to side EG.
How to determine a triangle according to its sides
In this question we have a triangle whose vertices are known. We need to define the figure according to the congruency among its sides. Two sides are congruent when both have the same length. There are three kinds of triangles:
Scalene - Three sides of different length.Isosceles - Two sides of equal length.Equilateral - All sides are of equal length.Sides are formed each pair of vertices. The length of each side can be found by means of Pythagorean theorem:
l = √[(Δx)² + (Δy)²]
First, write the locations of the vertices:
E(x, y) = (1, 4), F(x, y) = (5, 4), G(x, y) = (1, 0)
Second, determine the length of every side of the triangle:
EF = √[(5 - 1)² + (4 - 4)²]
EF = 4
FG = √[(1 - 5)² + (0 - 4)²]
FG = √[4² + (- 4)²]
FG = 4√2
EG = √[(1 - 1)² + (0 - 4)²]
EG = 4
By direct comparison, we conclude that the triangle EFG is an isosceles triangle.

Step-by-step explanation:
A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. Each small box of paper weighs 35 pounds
and each large box of paper weighs 65 pounds. What would be the total weight, in
pounds, of 10 small boxes and 15 large boxes? What would be the total weight, in
pounds, of s small boxes and I large boxes?
Answer:
1. What would be the total weight, in pounds, of 10 small boxes and 15 large boxes?
What you do is 10 * 35 + 15 * 65 = 350 + 975 = 1325 pounds
2. What would be the total weight, in pounds, of s small boxes and I large boxes?
35s + 65l would be the total weight

Answer:
Step-by-step explanation:
The diagram shows the position
of three towns represented by
letters A, B and C.
NA
B is 7 km from A on a bearing of 037°
C is 8 km from B on a bearing of 140°
Find the bearing of C from A.
Give your answer correct to 1 decimal place.
Answer:
Step-by-step explanation:
143º I’m not sure
The bearing of town C from town A is 93.3 degree if the B is 7 km from A on a bearing of 037° C is 8 km from B on a bearing of 140°
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
If we extend the line NA and NB
As we can see, line NA and NB are parallel and cut by transversal AB
The angle NBA and BAN' will be equal.
Angle BAN' = 180 - 37 = 143 degree = angle NBA
Angle CBA = 360 - 140 - 143
Angle CBA = 77 degree
Now, applying cos law:
b² = a² + c² - 2ac[cos B]
b² = (8)² + (7)² - 2(8 x 7 x cos77)
b = 9.37 km
To find the measure of the angle A applying sin law:
(sinA)/a = (sinB)/b
sinA = (axsinB)/b
sinA = (8xsin77)/9.37
A = 56.3⁰
Bearing of town C from town A:
α = A + 37⁰
α = 56.3⁰ + 37⁰
α = 93.3⁰
Thus, the bearing of town C from town A is 93.3 degree if the B is 7 km from A on a bearing of 037° C is 8 km from B on a bearing of 140°

Answer:
∠SAP = 85°
Step-by-step explanation:
The whole is the sum of the parts.
∠SAX = ∠SAP + ∠PAX
142° = ∠SAP + 57° . . . . . . . use the given values in the equation
∠SAP = 142° -57° . . . . . . . . subtract 57° from both sides
∠SAP = 85°

Lakiesha is an employee who drives a 2019 Buick Verano as a company car. The fair-market value of the car is $28,545. She has been given the choice to have her fringe benefit reported on her W-2 either using the lease-value rule or the cents-per mile rule. According to Publication 15-b, the lease value is $7,750. She has driven 4,500 miles for personal use and 31,250 miles in total during the year. The car has been available for use on 200 days during the year. Lakiesha's employer pays for all fuel. What method and valuation will yield the lowest fringe-benefit amount for Lakiesha? (Do not round intermediate calculations, only round final answer to two decimal points.)
Answer:
Lease value
Step-by-step explanation:
The lease value may bed defined as an open market capital valuation of the parts of the subject or the subject that are to be leased in regards of the terms of the lease.
In the context, Lakiesha drives a company car whose value is $ 7,750 according to 15-b publication. The car was available for 200 days in a year. She drove the car for 4500 miles for her personal use and 21250 miles in total. The fuel is paid by the employer. So here the best method that will yield the lowest fringe benefit amount for her is the lease value method.
