21. You place a mat around a 25 in by 21 inch painting as shown. The mat
is twice as wide at the left and right of the painting as it is at the top an
bottom of the painting. The area of the mat is 714 square iinches (note:
the area of the border). How wide is the mat at the left and right of the
painting? At the top and bottom of the painting? (P.264 #66)

Answers

Using a quadratic equation according to the area of the rectangular mat, it is found that:

At the top and bottom of the painting, the width is 0.654 inches.At the left and right of the painting, the width is of 1.308 inches.

The area of a rectangle of length l and width w is given by:

[tex]A = lw[/tex]

In this problem:

The length of the figure is of [tex]l = 25 + 4x[/tex].The width of the figure is of [tex]w = 21 + 2x[/tex].Area of 714 square inches, thus:

[tex]lw = 714[/tex]

[tex](25 + 4x)(21 + 2x) = 714[/tex]

[tex]8x^2 + 134x + 525 = 714[/tex]

[tex]8x^2 + 134x - 189 = 0[/tex]

Which is a quadratic equation with [tex]a = 8, b = 134, c = -189[/tex].

The, to find the widths of the mat, we have to first find the value of x, solving the quadratic equation.

[tex]\Delta = 134^2 - 4(8)(-189) = 24004 [/tex]

[tex]x_{1} = \frac{-134 + \sqrt{24004}}{2(8)} = 0.654[/tex]

[tex]x_{2} = \frac{-134 - \sqrt{24004}}{2(8)} = -9.03[/tex]

We are interest in the positive value of x, so x = 0.654.

At the top and bottom of the painting, the width is of 0.654 inches.

[tex]2(0.654) = 1.308[/tex]

At the left and right of the painting, the width is of 1.308 inches.

Which of the following are possible
side lengths for a triangle?
A. 9, 4,8
B. 14, 7,6
C. 3, 8, 1

Answers

a is your answer to the question that you are asking

The only set of side lengths that can form a triangle is 9, 4, 8.

Option A is the correct answer.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Let's check if each of the given sets of side lengths satisfies this condition:

9, 4, 8

9 + 4 > 8 ✓

9 + 8 > 4 ✓

4 + 8 > 9 ✓

All three inequalities are true, so these side lengths can form a triangle.

14, 7, 6

14 + 7 > 6 ✓

14 + 6 > 7 ✓

7 + 6 > 14 ✗

The last inequality is false, so these side lengths cannot form a triangle.

3, 8, 1

3 + 8 > 1 ✓

3 + 1 > 8 ✗

8 + 1 > 3 ✓

The second inequality is false, so these side lengths cannot form a triangle.

Therefore,

The only set of side lengths that can form a triangle is A. 9, 4, 8.

x² + 2ax + a² - a = 4 - x²

2x²+2ax+a²-a -4 =0

the equation has two different solutions

=> (2a)² - 4(2)(a²-a-4) > 0

4a²-8a²+8a +32 >0

What is 3/7÷2/7

Also 3/4÷5/6

Answers

Answer:

3/7 ÷ 2/7 = 3/2

3/4÷5/6 = 9/10

Step-by-step explanation:

The key rule to understanding how to divide fractions is...

KEEP SWITCH FLIP!!!

Basically, you keep the first fraction, switch the sign from division to multiplication, and flip the other fraction...

Here's how you would go about this:

3/7÷2/7

Keep 3/7 and switch ÷ to multiplication

3/7 · 2/7

Now flip 2/7 so it becomes 7/2

3/7 · 7/2

Now multiply across!

3 · 7 = 21

7 · 2 = 14

You get 21/14...but don't forget to simplify!! Divide 21 and 14 by 7 to get 3/2!

And now...for 3/4 ÷ 5/6, you do the exact same thing!

Keep...3/4

Switch... ÷

Flip...5/6

And you should get:

3/4 · 6/5

Multiply across...

= 18/20

Simplify!

= 9/10

I hope this helps clarify any confusion you may have had!

detailed explanation and answer please 20 points

Answers

Step-by-step explanation:

The first part of solving the area is multiplying the rectangle. So you do 15*18 which is 270. Then to solve a triangle you make it a square/rectangle. So it would be 8*15 which is 120. Because the length is the length of the rectangle and the width is shown on top. Then because it’s a rectangle not a triangle you divide by 2 because you were adding half to it when you were making it a rectangle. So it’s 120/2 which is 60. And 270+60 is 330. So the area is 330. To get the perimeter you add all the sides together. And because one of the sides is not added but half of the bottom line is the same length as the top so it would be 18+ the 8 on the top which is 26. So 15+18+17+26 is 76. So the perimeter is 76

So the answer is the bottom one. P=76 and A=330

Answer:

2323

Step-by-step explanation:

Mental math means to find a way to do this problem in your head without using paper, pencil or a calculator.

The question says there are 23 classes and each class is to collect 101 items.

The equation would be 23 x 101.

To do this in your head real quick, make the numbers easier to multiply.

Make the 101 items 100. That means you are telling each class to collect 1 less item or 23 less items total.

You can do this in your head real quick. 23 classes collecting 100 items is 2300 items.

You had each class collect 100 items instead of 101. That mean you didn't collect 23 items. So if you add those back in, you will get

2323 items.
