Liza needs help to solve this linear equation. 4(x – 5) + 2x = 9x – 2(4 + 2x) She has completed two steps, but now she's stuck. Examine her work. 1. 4x - 20 + 2x = 9x - 8 - 4x 2. 6x - 20 = 5x - 8 What could be the next step? Select all that apply. Add 8 to both sides. Add 5x to both sides. Subtract 6x from both sides. Subtract 20 from both sides. Divide both sides by –8. Divide both sides by –20
Answer:
Add 8 to both sides
Subtract 6x from both sides.
good luck i also did it on edge
To solve the given linear equation , next steps to be followed
1. Subtract 6x from both sides.
2. Add 8 to both sides.
What is linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
Given linear equation
4(x – 5) + 2x = 9x – 2(4 + 2x)
Step 1: 4x - 20 + 2x = 9x - 8 - 4x
Step 2: 6x - 20 = 5x - 8
Next step is Subtract 6x from both sides.
Step 3: 6x - 20 - 6x = 5x - 8 - 6x
⇒ -20 = -x - 8
Next step is Add 8 to both sides.
Step 4: -20 + 8 = -x - 8 + 8
⇒ -12 = -x
⇒ x = 12
Hence,
To solve the given linear equation , next steps to be followed
1. Subtract 6x from both sides.
2. Add 8 to both sides.

Write an equation and show your work: There were five different Foil Kites that each descend 50 feet per second for 5 seconds. Find the total change in altitude for all 5 kites.
Answer: Change in altitude = (50 x 5) feet
The total change in altitude for all 5 kites. = 250 feet
Step-by-step explanation:
Given : Rate of descent = 50 feet per second (speed)
Time = 5 seconds
Since, distance = speed x time
Change in altitude = Rate of descent x Time
Change in altitude = 50 x 5 feet [required equation]
= 250 feet
Hence, the total change in altitude for all 5 kites. = 250 feet

Avi’s dining room measures 124 square feet and is in the shape of a square. Which is the best estimate of the length of one side of the room, to the nearest tenth of a foot?
10.7 feet
10.9 feet
11.1 feet
11.4 feet
Answer:
11.1 feet
Step-by-step explanation:
because the formula for area of a square is A=L^2
so in this situation you would square root the 124 square feet, since all 4 sides are equal lenths
Answer:
The answer is C, 11.1 feet.
Step-by-step explanation:
To figure this out, you would estimate the square root of 124, since a square has sides of equal length. Your estimate would be closest to 11.1. I hope my answer helps, and if it does not, please leave a comment below, so that I can fix it.

A thin wire 40 CM long is formed into a rectangle if the width of this rectangle is 8 CM what is length and area
Length of a wire = 40 cm.
Breadth of the rectangle formed = 8 cm.
Find:length and area of rectangle.
Solution:Length of a wire = 40 cm.
A rectangle is made from this wire.
That means,
Perimeter of the rectangle formed = length of the wire.
Also,
Breadth of the rectangle formed = 8 cm.
We know that,
Perimeter of a rectangle = 2(length + breadth).
Let the length of the rectangle be x cm.
Hence,
→ 2(x + 8) = 40
→ 2x + 16 = 40
→ 2x = 40 - 16
→ 2x = 24
→ x = 24/2
→ x = 12
Hence,
Length of the rectangle formed = x = 12 cm.
Now,
We know,
Area of a rectangle =length * breadth
→ Area of the rectangle = (12) * (8)
→ Area of the rectangle = 96 cm²
Therefore, the area of the rectangle formed is 96 cm².
I hope it will help you.

Is the sum of the areas of two smaller squares equal to the area of a large square if the side lengths of the squares are 8 feet, 5 feet, and 3 feet? Note that the area of a square is s2, where s is the side length. Explain.
Answer:
No, the sum of the areas of two smaller squares is not equal to the area of a larger square if the lengths of sides of the squares are 8 feet, 5 feet and 3 feet.
Step-by-step explanation:
WE know that the area of a square is A = s² where s = length of side of the square. Now, since we have squares of varying sides of 8 feet, 5 feet and 3 feet respectively, we want to determine if the areas of the two smaller squares equals that of the larger square. Let A = area of 8 feet side square, A' = area of 5 feet side square and A" = area of 3 feet side square. We want to show if A = A' + A".
Now A = (8 ft)² = 64 ft²
A' = (5 ft)² = 25 ft² and
A" = (3 ft)² = 9 ft²
A' + A" = 25 ft² + 9 ft² = 36 ft²
Since L.H.S = 64 ft²and R.H.S = 36 ft²
So, 64 ft² ≠ 36 ft²
L.H.S ≠ R.H.S
So, the sum of the areas of two smaller squares is not equal to the area of a larger square if the lengths of sides of the squares are 8 feet, 5 feet and 3 feet.

B
12x = 180
С
12x - 20 = 180
D
8x - 10 = 4x + 10
Answer:
B
Step-by-step explanation:
4x+10+6x-10+2x=180°
4x+6x+2x=180°+10-10
12x/12=180°12
x=15° check :
4x+10+6x-10+2x=180° then x=15°
4*15+10+6*15-10+2*15=180°
60+10+90-10+30=180°
180°=180°
The equation representing the value of x is 12x + 20 = 180
What is a triangle?A triangle is a polygon with three edges and three vertices.
Given that, a triangle having interiors angles, 2x, 4x + 10 and 6x - 10
We know that, the sum of the interior angles of the triangle = 180°
Therefore,
2x + 4x + 10 + 6x - 10 = 180°
12x + 20 = 180°
Hence, the equation representing the value of x is 12x + 20 = 180
