Which expression can you simplify by combining like terms?
1 answer:
Answer:
The correct option is A.
Step-by-step explanation:
If the degree and variables of two terms are same, then they are called like terms.
In option A.
The given expression is
Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.
By combining like terms we get
In options B, C and D, there are no like terms, So only the expression we can simplify by combining like terms.
Therefore the correct option is A.

Answer:
The fair price for the large container is<u><em> $12</em></u>
Step-by-step explanation:
In this question, we are tasked with calculating what would be the fair price for the large cylinder given the price for the small cylinder.
To calculate this, what we need to do firstly is to estimate the the volumes of both cylinders.
Mathematically, the volume of a cylinder can be calculated using the formula; V = π ××h
For the small cylinder, r = 3 inches and h = 10 inches
Thus = π ×
× 10 = 90π
For the large cylinder, r = 6 inches and h = 10 inches
Thus = π ×
× 10 = 360π
Now let us find the ratio of their volumes = 360π/90π = 4
Since the ratio of their volumes is 4, it can be fair to say that the large cylinder should cost 4 times the price of the small cylinder = 4 × $3 = $12
