The expression shown is the cost a custom pays for an item, where c is the cost the store which expression is equivalent c+0.85c? a. 0.15c b. 0.85c c. 1.15c d. 1.85c guys i need this !

Option D.

Step-by-step explanation:

You know that the expression given in the exercise represents the cost a custom pays for an item. This is:

As you can see, the expression has two terms, and the variable is the cost c.

The variable of the first term is c and the coefficient is 1.

The variable of the second term is c and the coefficient is 0.85

As both are like terms, you can add the coefficients. Therefore, you obtain the following equivalent expression:

345

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
