Find the value of X, then find AB and DC.
(opposite sides are congruent)
AB= 3x+8
DC= x+12

Find The Value Of X, Then Find AB And DC. (opposite Sides Are Congruent)AB= 3x+8 DC= X+12

Answers

Answer 1

Answer:

x = 2

AB = 14

DC = 14

Step-by-step explanation:

If opposite sides are congruent, then:

AB = DC

AB = 3x + 8

DC = x + 12

Thus:

3x + 8 = x + 12

Collect like terms

3x - x = -8 + 12

2x = 4

Divide both sides by 2

x = 2

AB = 3x + 8

Plug in the value of x

AB = 3(2) + 8 = 14

DC = x + 12

Plug in the value of x

DC = 2 + 12 = 14

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Two lines are drawn in the same plane.

If the two lines intersect then the angle between the line is 90 degrees.

The condition for the lines to be perpendicular will be two lines that intersect and form right angles.

Then the correct option is B.

ANOVA is a hypothesis testing technique used to compare the equality of means for two or more groups; for example, it can be used to test that the mean number of computer chips produced by a company on each of the day, evening, and night shifts is the same. Give an example of an application of ANOVA in an industrial setting that is different from the examples provided in the course. Discuss and share this information with your classmates.

Answers

Answer:

The answer is below

Step-by-step explanation:

ANOVA can be used in a construction industry whereby the construction or project manager is saddled with the responsibility of picking the most appropriate method of construction or materials to be used during construction in the face of two or more alternative options.

For example in terms of method of construction, two or three methods of construction may be available to pick from to construct a building project.

However, due to the possibility of differences in construction cost, and project duration. The construction manager may need to use an ANOVA test to determine the project duration of each method and if it is later revealed through the test that all the methods of construction will lead to the project being delivered on time as the client scheduled.

Then, the construction manager may then result to pick the least expensive alternative of the construction methods.
