Answer:
24x - 16
Step-by-step explanation
What we're doing here is factorisation
To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).
First,
-4 x -6x
-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.
You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!
Next,
Multipying the outside number by the second inside again:
-4 x 4 = -16
Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.
Finally,
Connect both of these answers
24x - 16 is the answer!
(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?
Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
120km
Step-by-step explanation:
let s = the original speed
Write a distance equation; dist = time * speed
3(s-10) = 2(s+10)
3s - 30 = 2s + 20
3s - 2s = 20 + 30
s = 50 km/hr is the original speed
confirm this, find the distances
3(50-10) = 120 km
2(50+10) = 120 km

Abby is painting two cubes for an art project.
Cube 1: side length = 3 feet
Cube 2: side length = 2 feet
The surface area of a cube is 6s2, where s is the length of one side.
Find the total surface area that Abby will paint.
1. Find the surface area of cube 1. Show your work, and include units with your answer.
2. Find the surface area of cube 2. Show your work, and include units with your answer.
3. What is the total area Abby will paint?
Answer:
54 sq ft, 24 sq ft, 78 sq ft
Step-by-step explanation:
1. Each side of cube 1 is 3 feet x 3 feet, so each side has an area of 9 square feet. Multiply by 6 sides and the area is 54 square feet.
2. Each side is 2 feet x 2 feet so the area of one side is 4 square feet. Multiply by 6 sides and the area is 24 square feet.
3. 54 + 24 = 78 square feet

Find the quotient. Express your answer as a simplified fraction. 3/10 divided by 3.8
Answer:
4/5
Step-by-step explanation:
3/10÷3/8
=(3×8)/(10×3)
=24/30
Simplifying 24/30, the answer is
=4/5
The value of the quotient of ''3/10 divided by 3.8'' as a simplified fraction would be 3/38.
Given that;
The expression is,
3/10 divided by 3.8
Now it can be divided as,
3/10 divided by 3.8
3/10 ÷ 3.8
3/10 × 1/3.8
3/38
Therefore, the value of the quotient as a simplified fraction would be 3/38.

You just found the car of your dreams. It will cost $24,000. You have been saving for a car since 3rd grade and now have $6,000. Your dad will match that with another $6,000 for the car. You will pay a simple interest of 10% on the balance of what you owe after you give the car dealership the money you have between your dad and yourself.
How much money will you still owe?
Answer:
I think the answer is 13,200
Step-by-step explanation:
6k+6k=12,000 half of the price of the car
.10x12000= 10% interest = 1200 + rest of the balance(12,000)=13,200
