Write the equivalent expression for 6x + 5y + 7x a. 18xy b. 30xy c. 11xy + 7y d. 13x + 5y

Step-by-step explanation:

The first step is to determine if some of the terms can be combined (added), so you have to look for like terms (like terms have the same variables with the same exponent).

We have the expression:

We can see that there are two elements that contain x ( and ) , this means that they are like terms and we can add them:

⇒

and this would be the final result, since there are no more like terms in this expression. The answer is D.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
