If Triangle Abc Is Similar To Triangle Edc Find The Value Of X

Answers

Answer 1

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{BC}{DC}[/tex] = [tex]\frac{AC}{EC}[/tex] , substitute values

[tex]\frac{3x-5}{32}[/tex] = [tex]\frac{5x-5}{56}[/tex] ( cross- multiply )

56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides

168x - 280 = 160x - 160 ( subtract 160x from both sides )

8x - 280 = - 160 ( add 280 to both sides )

8x = 120 ( divide both sides by 8 )

x = 15

A.

B.
(x − 10)2 = 21
C.
(x − 10)2 = 36
D.
(x − 5)2 = 36

Answers

Answer:

D. [tex]\displaystyle (x - 5)^2 = 36[/tex]

Step-by-step explanation:

All you are doing is converting this Quadratic Equation to a Vertex Equation in Vertex Form by completing the square:

[tex]\displaystyle [\frac{b}{2}]^2 \\ \\ x^2 - 10x - 11 = 0 → x^2 - 10x + 25 - 36 = 0→ (x - 5)^2 - 36 = 0 \\ \\ (x - 5)^2 = 36[/tex]

It is that simple, is it not?

A painting measures 2.4 feet from left to right. It’s hung in the center of a rectangular wall measuring 20 feet from left to right. What is the distance between the right edge of the painting and the right edge of the wall? Assume that the painting does not tilt.
A. 7.6 feet
B. 8.8 feet
C. 17.6 feet
D. 18.8 feet

Answers

So you want to figure out how much wall space isn’t covered by the painting, so 20-2.4. Then you need to divide your answer by 2 because it is in the center of the wall. So your answer is B. 8.8 feet hope that helps!

B) 8.8

(20-2.4)/2 = 8.8

Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.

Answers

Answer:

52 ft

Step-by-step explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:

Answer:

52m

Step-by-step explanation:

Area of the square floor = 169 m²

For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.

So,

Length of each side of floor = √169 = 13m

For a square with each side 's' , its perimeter will be 4s.

Hence ,

Perimeter of the kitchen = 13 × 4 = 52m

The difference of two numbers is 18. Their sum is 66. What are the numbers? List the numbers from least to greatest.

Answers


attack_panic

5y
Another solution is to solve one equation for one variable, and plug that into the other equation.

x + y = 66
x = 66 - y

(66 - y) - y = 18
66 - 2y = 18
-2y = 18 - 66
-2y = -42
-2y/-2 = -42/-2
y = 24

Now that you have y, plug that into the first equation and solve for x.

x + 24 = 66
x = 66 - 24
x = 42

Then plug your two answers into both original equations to verify.

x + y = 66
42 + 24 = 66
66 = 66 check

x - y = 18
42 - 24 = 18
18 = 18 check

Sorry, I tried.

Hope this helps.

Step-by-step explanation:

The chosen topic is not meant for use with this type of problem. Try the examples below.

6x2+3y2=126x2+3y2=12 , x+y=2x+y=2

x+2y=4x+2y=4 , x−y=−3x-y=-3

x2−y=2x2-y=2 , 2x−y=−12x-y=-1

Y:
-5y + 87 = -18
-5y = -18 - 87
-5y = -180
y = -180 / -5
y = +36

X:
( 5 x 36 ) + 2x = 58

180 + 2x = 58

2x = 58 - 180

2x = -122

x = -122 / 2

x = -61
