I'm going to assume the 4 and 3 are exponents and the expression is .
The first step is to separate the coefficients of 3 and -6 from the variables and to multiply those as normal:
As for the variables, you want to recognize that means and means , so
In total, there are 7 a's being multiplied, so
Putting this all together, we have:

Answer:
hello welcome to brainly here's your answer
Step-by-step explanation:
Let One Cup of Coffee is X and one doughnut be Y
So X+3Y=4.10 and 2X+2Y=4.60 => X +Y=2.30
=> X+3Y-(X+Y)=4.10-2.30 => 2Y=1.80 => Y=0.90
and X+0,90=2.30 => X=2.30-0.90=1.40
So answer is 1 cup of coffee is $1.40 and one doughnut is $0.90
180° = sum interior angles
180 : (2 + 3 + 4) * 4 =
180 : 9 * 4 =
20 * 4 =
80° (value of x)
