Is the following shape a rectangle how do you know a. there is not enough information to determine
b. no, the opposite sides are not parallel
c. no the adjacent sides are not perpendicular
d. yes the adjacent sides are perpendicular and the opposite sides are parallel

Yes, the adjacent sides are perpendicular, and the opposite sides

are parallel.

Step-by-step explanation:

because when adjacent sides are perpendicular and the opposite sides are parallel and opposite sides are equal but adjacent side are not equal then it is rectangleI hope it helps you

the answer is b

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 : )
