Correct Answer: 2x^2
Explanation:
In an algebraic expression, like terms are terms that contain the same variables raised to the same powers. Calculating x-squared plus x-squared is a matter of combining like terms.
Now x^2 + x^2 = 2x^2
Hence, x-squared plus x-squared is equal to 2 times x squared.
Correct Answer: 32
Correct Answer: 143
Correct Answer: 3/8
Explanation:
Now to find the difference in the given fractions, 1/2 - 1/8
First take the LCM of 2 & 8
LCM of 2 & 8 is 8
Then,
1/2 - 1/8
= (4 - 1)/8
= 3/8
Hence, 1/2 - 1/8 = 3/8.
Correct Answer: -1
Explanation:
