Answer:
-44ax^2-198x^2+66a+297
Step-by-step explanation:
there
For part A: the constant is 83.50. the variable would be c and w. and the coefficient would be 10c or 15w.
part B: so 10(4)+15(15)+83.50 -----> 10x4= 40------> 40+15(15)+83.50---->15x15=225
40+225+83.50=348.50
part C The coefficient would change because a constant is always constant, a variable is just a letter standing in for a number which would make the coefficient the one that changes for $10 to $20.
hope that help!
You circle the points on both sides and then you calculate them and get what you need...
Is there an equation with the question? This doesn't mean anything^
