Part A: The area of a square is (9x2 − 12x + 4) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work. (5 points) Part B: The area of a rectangle is (25x2 − 16y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)

Side of square =

Dimensions of rectangle are

Step-by-step explanation:

Given: Area of square is and area of rectangle is

To find: dimensions of the square and rectangle by factoring the area expression completely.

Solution:

Area of square is given by

So,

Hence, side of square =

(Use formula )

Also, area of rectangle = length × breadth

So,

length × breadth =

So, dimensions of rectangle are

the thermometer is precise but not accurate

step-by-step explanation:

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 : )
