4 sweets cost 28p altogether
28÷4=7p for each sweet
If each sweet costs 7p, then 7 sweets would be multiplied by 7
7×7p=49p
7 sweets cost 49p
I think the answer is c but let me look it up
35. 20+15=30. 2 tens=20+15 hope this helps!
First factor the second fraction's denominator.
It is a difference of squares so it can be factored as (y + 4)(y - 4)
Notice the first fraction's denominator is y + 4. So you already have that.
Therefore the LCD is (y + 4)(y - 4) :)
The answer is:
The explanation of this exercise is shown below:
1. You have the following expression given in the problem above:
2. By the exponents properties, when you multiply powers with the same base, you must sum the exponents. In this case the base is , therefore, you must sum the exponents.
3. The result of the sum is 6, therefore, must be 4:
