The temperature one winter morning is -8°F. Define a variable and write an expression to find the temperature after the chang below. Then evaluate your expression for the change.
a rise of 7°F
A. c= change in temperature; - 8 - 9 -15°F
B. c= change in temperature; -8 + 61°F
C. c= change in temperature; -8 + C -1°F

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
