Answer:

length = x+6

width = x-6

Step-by-step explanation:

The area of rectangle is:

[tex] \displaystyle \large{ A= l \times w}[/tex]

where A is area, l is length and w is width.

We know the area of this rectangle or table since we are given A = x^2-36.

First, substitute A = x^2-36 in.

[tex] \displaystyle \large{ {x}^{2} - 36 = lw}[/tex]

Then we factor x^2-36, use the difference of two squares:

[tex] \displaystyle \large{ (x + 6)(x - 6) = lw}[/tex]

Compare the terms.

First, we have to understand that length is always longer or greater or have more values than width.

Hence length cannot be x-6 and width cannot be x+6 either.

Thus:

[tex] \displaystyle \large{length = x + 6} \\ \displaystyle \large{width = x - 6}[/tex]

Answers

Answer:

to get which one is the best we have to bring them packages to the same terms

so to do that we have to find what each package offers per month by divided the amount by the number of months

so

160/4= 40

128/4=32

60/2=30

so the best package is

B. package 1

What do all similar circles have in common?

Answers

Answer:

Explanations (4) Similarity is a quality of scaling: two shapes are similar if you can scale one to be like the other, like these triangles ABC and DEF. Since all circles are of the same shape (they only vary by size), any circle can be scaled to form any other circle. Thus, all circles are similar!

If c-d=7 and c=3-8i what is d

Answers

Answer:

d=-4.......,...........

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

If,

c - d = 7

c = 3 - 8i

The value of  d is -4 - 8i

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 4 is an equation.

2x + 6 is an equation.

We have,

Two equations:

c - d = 7 _______(1)

c = 3 - 8i _______(2)

We are using the substitution method to solve this problem.

We make the value of a variable from an equation and substitute the value of that variable in the other equation.

From (1) we get,

c - d = 7

Add d on both sides.

c - d + d = 7 + d

c = 7 + d ______(3)

Put (3) on (2) we get,

7 + d = 3 - 8i

Subtract 7 on both sides.

7 + d - 7 = 3 - 8i - 7

d = -4 - 8i

Thus,

If,

c - d = 7

c = 3 - 8i

The value of  d is -4 - 8i

Use the information given to write an equation in standard form.

6. Slope is 3, and (1. 4) is on the line.

7. Slope is -2, and (4,3) is on the line.

10. Slope is , and (1, 3) is on the line.

11. Slope - , and (2, 3) is on the line

Answers

The correct answers are:

6. 3x-y=-1

In slope intercept form this equation has a slope of 3 and point 1,4 is included on the graphed line: y=3x+1 is slope intercept form.

7. 2x+y=11

In slope intercept form this equation has a slope of -2 and point 4,3 is included on the graphed line: y=-2x+11 is slope intercept form

10. 4x-7y=-17

In slope intercept form this equation has a slope of 4/7 and point 1,3 is included on the graphed line: y=4/7x+17/7 is slope intercept form


11. 3x+2y=12

In slope intercept form this equation has a slope of -3/2 and point 2,3 is included on the graphed line: y=-3/2x+6 is slope intercept form


You basically just find the slope intercept form of each question then convert the intercept form over to standard form then graph in intercept form to see if the point lies on the line :)

The cost of the wire of the third length in the table is, 25 dollars

We have to give that,

The cost of a certain type of wire varies directly with its length.

Now, From the table the equation between cost and length is,

y - 15 = (20 - 15)/(8 - 6) (x - 6)

y - 15 = (5/2) (x - 6)

y - 15 = 2.5x - 15

y = 2.5x

Where y represents the cost and x represent the length.

Hence, At x = 10 feet

y = 2.5 (10)

y = 25 dollars

So, The cost of the wire is, 25 dollars
