That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.
Answer:
77.5 cm²
Step-by-step explanation:
We need to find the surface area of the rectangular prism.
Total surface area = 2(lw + wh + lh)
where:
- l = length of base
- w = width of base
- h = height of prism
Given dimensions:
Substituting these value into the formula:
Therefore, 77.5 cm² of fabric is needed to cover the weight.
[6] ([3] + [50])
Just make sure you understand how to work backward with problems like this if you are ever confused. :)) good luck!!
Answer:
D
Step-by-step explanation:
Tips = 15.50 - 12.50 = 3.00
Covert the tips to percentage
3 ÷ 12.50 x100% = 24%
It is more than 20%
