Answer:
-3
Step-by-step explanation:
Note the right side of the equation. There is a negative sign outside of the parenthesis. Distribute the negative sign to all terms within the parenthesis:
x + 3 = - (-x + __)
x + 3 = x - ___
Note:
1) When multiplying a negative and positive together, the answer will be negative
2) When multiplying a negative and negative together, the answer will be positive:
x + 3 = x - ___
Note the equal sign, this means that the two side of the equation must equal. This means that the only answer choice is -3:
x + 3 = x - (-3)
x + 3 = x + 3 (True)

This should be a nice and simple answer to your question.
The formula for working out the volume of a cuboid is
Volume=Length×Width×Height
This can be shortened to
V=l×w×h
Or
V=lwh
So, now you know the formula, on to the question
Work out the volume of a cuboid 6cm by 4cm by 2.5cm
Find the relevant information
6cm 4cm and 2.5cm
Write out the formula
V=l×w×h
Substitute in the values
V=6×4×2.5
Solve the equation
V=60
Volume is always a cubed number so remember to add the cubed sign next to your answer (³)
So your final answer will be
Volume=60³
I hope that this has helped you.
Answer:
24 :)
Step-by-step explanation:
12 divided by 3 = 4
24 divided by 3 = 8
36 divided by 3 = 12
4 + 8 = 12
12 + 12 = 24
12 would be the unit rate you mulitply 3 × 4
65 ÷ 1.5 = 43.333333...
Hope this helps you!
Always remember you are a Work Of Art!
