Correct Answer: 2X^2
Explanation:
Here the given expression,
is an algebraic expression. Here in this expression the terms are like terms. Now to add them, add their coefficients.
Here in the given expression, the like terms are two
Hence, adding their coefficients i.e, 1 + 1 = 2
Therefore,
= 2 .
Correct Answer: 4.5
Explanation:
Given equation is
Here it is in the form of
Here m = 2.5 , n = p, m+n = 7
=> 2.5 + p = 7
=> p = 7 - 2.5
=> p = 4.5
Correct Answer: 50
Explanation:
Given 7 + 7/7 + 7 x 7 - 7
By using BODMAS rule,
7 + 1 + 7 x 7 - 7
= 8 + 49 - 7
= 57 - 7
= 50.
Hence 7 + 7/7 + 7 x 7 - 7 = 50.
Correct Answer: 548
Explanation:
? = 5068 x 4/37
? = 548
Correct Answer: 12
Explanation:
Using BODMAS law,
3 x 3 + 3 - 3 + 3 =
3 x 3 = 12
= 12 + 3 - 3 + 3
= 9 + 3
= 12
Hence, 3 x 3 + 3 - 3 + 3 = 12.
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: 143
Correct Answer: 32
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: 1
