BD = DC because angles ADC and ADB are right angles.
Thus, [tex]4x-5=2x+7[/tex]
Add 5 to both sides:
[tex]4x-5+5=2x+7+5[/tex]
[tex]4x=2x+12[/tex]
Subtract 2x from both sides:
[tex]4x-2x=2x+12-2x[/tex]
[tex]2x=12[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=\frac{12}{2}[/tex]
[tex]x=6[/tex]
DC [tex]=4x-5[/tex]
[tex]=4(6)-5[/tex]

Solve the following equation. Show all steps.
4(3y – 6) = – 3(8 – 4y)
Answers
Answer:
0=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(3y−6)=−3(8−4y)
(4)(3y)+(4)(−6)=(−3)(8)+(−3)(−4y)(Distribute)
12y+−24=−24+12y
12y−24=12y−24
Step 2: Subtract 12y from both sides.
12y−24−12y=12y−24−12y
−24=−24
Step 3: Add 24 to both sides.
−24+24=−24+24
Answer:
All real numbers
Step-by-step explanation:
So we have the equation:
[tex]4(3y-6)=-3(8-4y)[/tex]
First, distribute the left side:
[tex]12y-24=-3(8-4y)[/tex]
Now, distribute the right:
[tex]12y-24=-24+12y[/tex]
Subtract 12y from both sides. Both sides cancel:
[tex]-24=-24[/tex]
This statement is true.
In other words, our solution is all real numbers.

A crayon is 4 inches long. A wooden board is 8 feet long. Which diagram and statement best represents their lengths?
Answers
The wooden board is 24 times the length of Crayon which is represented by Figure C.
We have,
A crayon is 4 inches long.
A wooden board is 8 feet long.
We know that
1 feet = 12 inch
So, 8 feet = 12 x 8 = 96 inches
Now, the factor between Caron and wooden block
= 96 / 4
= 24
Thus, the wooden board is 24 times the length of Crayon which is represented by Figure C.

An olympic-size swimming pool is a rectangle that measures 50 meters in length and 25 meters in width. Make a scale drawing of an olympic-size swimming pool where 1 centimeter represents 5 meters. What are the length and width of your scale drawing?
Answers
Answer:
Length: 10 cm
Width: 5 cm
Step-by-step explanation:
The required length and width of the scale drawing are given a length will be 10 cm and the width will be 5 cm.
Given that,
A swimming pool of rectangle shape that measures 50 meters in length and 25 meters in width. To make a scale drawing of an Olympic-size swimming pool where 1 centimeter represents 5 meters.
The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
Given scale: 1 cm = 5 m
So, for 1 m = 1/5 cm
Now,
Length = 50 × 1/5 = 10 cm
Width = 25 × 1/5 = 5 cm
Thus, the required length and width of the scale drawing is given a length will be 10 cm and a width will be 5 cm.

Answer:
p = -7
a = 10
Step-by-step explanation:
Question 1:
Step 1: Write out equation
-22 = 12p - 2(5p + 4)
Step 2: Distribute
-22 = 12p - 10p - 8
Step 3: Combine like terms (p)
-22 = 2p - 8
Step 4: Add 8 to both sides
-14 = 2p
Step 5: Divide both sides by 2
-7 = p
Step 6: Rewrite
p = -7
Question 2:
Step 1: Write out equation
11a - (4a - 7) = 77
Step 2: Distribute
11a - 4a + 7 = 77
Step 3: Combine like terms (a)
7a + 7 = 77
Step 4: Subtract 7 on both sides
7a = 70
Step 5: Divide both sides by 7
a = 10

the corners of a meadow are shown on a coordinate grid. Ethan wants to fence the meadow. What length of fencing is required?
On the grid: Point A (-6,2); Point B (2,6); Point C (7,1); Point D (3,-5)
Answers
Answer:
34.6 units
Step-by-step explanation:
The lenght of fencing required is the total distance between point A to B, B to C, C to D, and D to A. That is the distance between all 4 corners of the meadow.
The coordinates of the corners of the meadow is shown on a coordinate plane in the attachment. (See attachment below).
Let's use the distance formula to calculate the distance between the 4 corners of the meadow using their coordinates as follows:
Distance between point A(-6, 2) and point B(2, 6):
[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] A(-6, 2)) = (x_1, y_1) [/tex]
[tex] B(2, 6) = (x_2, y_2) [/tex]
[tex] AB = \sqrt{(2 - (-6))^2 + (6 - 2)^2} [/tex]
[tex] AB = \sqrt{(8)^2 + (4)^2} [/tex]
[tex] AB = \sqrt{64 + 16} = \sqrt{80} [/tex]
[tex] AB = 8.9 [/tex] (nearest tenth)
Distance between B(2, 6) and C(7, 1):
[tex] BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] B(2, 6) = (x_1, y_1) [/tex]
[tex] C(7, 1) = (x_2, y_2) [/tex]
[tex] BC = \sqrt{(7 - 2)^2 + (1 - 6)^2} [/tex]
[tex] BC = \sqrt{(5)^2 + (-5)^2} [/tex]
[tex] BC = \sqrt{25 + 25} = \sqrt{50} [/tex]
[tex] BC = 7.1 [/tex] (nearest tenth)
Distance between C(7, 1) and D(3, -5):
[tex] CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] C(7, 1) = (x_1, y_1) [/tex]
[tex] D(3, -5) = (x_2, y_2) [/tex]
[tex] CD = \sqrt{(3 - 7)^2 + (-5 - 1)^2} [/tex]
[tex] CD = \sqrt{(-4)^2 + (-6)^2} [/tex]
[tex] CD = \sqrt{16 + 36} = \sqrt{52} [/tex]
[tex] CD = 7.2 [/tex] (nearest tenth)
Distance between D(3, -5) and A(-6, 2):
[tex] DA = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] D(3, -5) = (x_1, y_1) [/tex]
[tex] A(-6, 2) = (x_2, y_2) [/tex]
[tex] DA = \sqrt{(-6 - 3)^2 + (2 - (-5))^2} [/tex]
[tex] DA = \sqrt{(-9)^2 + (7)^2} [/tex]
[tex] DA = \sqrt{81 + 49} = \sqrt{130} [/tex]
[tex] DA = 11.4 [/tex] (nearest tenth)
Length of fencing required = 8.9 + 7.1 + 7.2 + 11.4 = 34.6 units

Answer:

Step-by-step explanation:
Given that:
[tex]\lim_{x \to -5} \dfrac{(x+5)}{(x^3+125)}[/tex]
[tex](x^3 + 125) = (x+5)(x^2 -5x+25)[/tex]
Thus;
[tex]= \lim_{x \to -5} \dfrac{(x+5)}{(x+5)(x^2 -5x +25)}[/tex]
[tex]= \lim_{x \to -5} \dfrac{1}{(x^2 -5x +25)}[/tex]
[tex]= \dfrac{1}{((-5)^2 -5(-5) +25)}[/tex]
[tex]= \dfrac{1}{(25 +25 +25)}[/tex]
