Gwendolyn is asked to solve the equation −4(x−3)=20. She shows the work below and states that the solution is x=−8. −4(x−3)=20−4x+12=20−4x=32x=−8 Unfortunately, Gwendolyn's work is flawed. Explain the flaw in Gwendolyn's work. Determine the correct solution to the equation.
Answers
Step-by-step explanation:
The equation is given as;
−4(x−3)=20
Gwendolyn's flaw is in the following lines;
−4x + 12 = 20
−4x = 32
When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12
The correct solution is given as follows;
Step 1: Expand the brackets
This results to;
- 4x - (-4 * 3) = 20
-4x + 12 = 20
Step 2: Collect like terms
This results to;
- 4x = 20 - 12
- 4x = 8
Step 3: Solve for x
x = 8 / (-4)
x = -2

36-4+1 32+1 31
i hope this helps you!
Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answers
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A right-angle triangle has sides with lengths 200 ft and 200 ft.
By Pythagoras theorem, we have
H² = P² + B²
H² = 200² + 200²
H² = 40000 + 40000
H² = 80000
H = 200√2
H = 282.84 ft
Alma is going to walk through the park from Point A to Point B is 282.84 ft.
