Answer: To simplify an expression means to write an equivalent expression which contains no similar terms. This means that we will rewrite the expression with the fewest terms possible.
Step-by-step explanation: Hope this helps some

Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4

Pulg in 2 into the equation x+3^2
I dont know if theres supposed to be a parenthese like but if there isn't then it would be 2+ which is 2+9
if there is parenthese... it would be:
= =25
Answer:
The customer will pay 385.45
Step-by-step explanation:
∵ The cost is 299.95
∵ Its marked up by 85.50
∴ The customer will pay = 299.95 + 85.5 = 385.45
180 degree rotation negates both coordinates, and takes a point from quadrant 2 to quadrant 4.
Answer: 4
We can also rotate 180 degrees clockwise, or 540 degrees counterclockwise and end up in the same place.
Combining transformations, we can reflect in the x axis and then in the y axis, also negating both coordinates so equivalent to 180 degree rotation.
