Answer:

  39 units

Step-by-step explanation:

The angle markings tell you this is an equilateral triangle, so all sides are the same length.

  10x -11 = 2x +29

  8x = 40

  x = 5

Then the side length is ...

  2x +29 = 2·5 +29 = 39

The length of side KL is 39 units.

Answer:

Step-by-step explanation:

120 = 2x + 70

120  - 70 = 2x + 70 - 70

50 = 2x

50/2 = 2x/2

x = 25

Answer:

[tex]\sqrt{125}[/tex]

Step-by-step explanation:

Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]

225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]

Answer:

x = 5[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

x² + 10² = 15²

x² + 100 = 225 ( subtract 100 from both sides )

x² = 125 ( take the square root of both sides )

x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form

Answer:

C. x = 1

Step-by-step explanation:

Combine like terms

10 + 2 − 3 = 9

12 − 3 = 9

Add 3 to both sides of the equation

12 − 3 + 3 = 9 + 3

Add the numbers

12 = 9 + 3

12 = 12

[tex]\frac{12x}{12} = \frac{12}{12}[/tex]

Cancel terms that are in both the numerator and denominator

[tex]x = \frac{12}{12}[/tex]

Divide the numbers

x = 1

Therefore the correct answer is C. x = 1

Answer:

C. x = 1

The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?

Answer:

16 sides

Step-by-step explanation:

The sum of angles in a polygon formula is given as:

(n - 2)180°

Where n = Number of sides of the polygon

Hence:

(n - 2)180°= 2520°

Divide both side by 180°

(n -2) = 2520/180

n - 2 = 14

n = 14 + 2 = 16

Therefore the number of sides the convex polygon has 16 sides.

The expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

In order to calculate the expression, we need to use the PEMDAS rule which states:

From the question, we are to get the expression equal to 13.

From the given expression,(18 ÷ 2) + 6 ÷ 6 + 3 is equivalent to 13;

(18 ÷ 2) + 6 ÷ 6 + 3

9 + 6  ÷ 6 + 3

9 + 1 + 3

13

Hence the expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

Answer:

The coordinates of the new triangle would be (2,2), (-1,0) and (-2,4)

Answer: 80

Step-by-step explanation:

If you look at the top left and bottom right corner, you see that they are identical, so basically you would do the same to 80.

Well lets see...

Solution 1. The sum of angles of a quadrilateral is 360˚ 100˚+100˚+80˚=280 degrees 360˚-280˚=80˚.

Solution 2. Opposite angles on a parallelogram are equal so x=80˚.

= £27,000 ÷ 1,495 hours

= £18.06

Answer:

It’s B

Step-by-step explanation:

Because the area is 64 and the base is 4, then you would have to divide 64 by 4 to get 16 which is the height!

Answer:

it would be C. h=32 cm

Step-by-step explanation:

the formula for area of a triangle in A=1/2*b*h

so plug what you know into the formula, you know the area, A, and the base, b, so:

64=1/2*(4)*h

now solve what you can:

64=2h

then divide each side by 2 to get h, or the height, alone:

32=h

so, the height is 32 cm!

Answer:

You should by 17 bundles of shingles.

Step-by-step explanation:

540 divided by 32 is 16.875.

So, you will need almost 17 bundles.

If you were to only buy 16, you would not have enough.

Answer:

The least common denominator of the two rational expressions is [tex](x+2)^{2}\cdot (x+3)[/tex].

Step-by-step explanation:

Let be the following rational expressions:

[tex]\frac{x^{3}}{x^{2}+4\cdot x + 4}, \frac{-9}{x^{2}+5\cdot x + 6}[/tex]

Then, we factor each denominator:

[tex]\frac{x^{3}}{(x+2)^{2}}, \frac{-9}{(x+3)\cdot (x+2)}[/tex]

Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:

[tex]\frac{x^{3}}{(x+2)^{2}} \rightarrow (x+3)[/tex]

[tex]\frac{-9}{(x+3)\cdot (x+2)} \rightarrow (x+2)[/tex]

Hence, we conclude that least common denominator of the two rational expressions is [tex](x+2)^{2}\cdot (x+3)[/tex].
