Q. Which expression is equivalent to 5x+2x?Choices:(A) 7x(B) x7(C) 8x(D) x+7
Identify Like Terms: To find the equivalent expression, we need to combine like terms. The like terms in this expression are 5x and 2x, since they both have the variable x raised to the same power (which is 1).
Combine Coefficients: We add the coefficients of the like terms together: 5+2=7. Therefore, 5x+2x=7x.
Compare with Choices: Now we compare our result with the given choices to find the equivalent expression.(A) 7x(B) x7(C) 8x(D) x+7The correct choice that matches our result is (A) 7x.
