Question

What is the sum? 6x7 + 8x7 A. 14x7 B. -2x7 C. 14x 14 D. 48x 7

Answer 1

The answer is C because you add 6x and 8x to get 14 and 7+7 is also 14

Answer 2

Answer:

option A :$14 x^7$

Explanation:

We are given that $6x^7+8x^7$

We have to find the sum

Sum of algebraic expression

First  we see that given terms are like or not

If the terms are like terms then

We take variable common then we get

$(6+8)x^7$

$6x^7+8x^7=14 x^7$

Then the coefficient will be added and the variable remain same

Hence,the option A is true.
