Which statement is true about the composite solid?
The solid has a total of 9 faces
There are the same number of triangular faces as there are rectangular faces,
The solid is formed by joining a rectangular pyramid and a triangular prism at a common face
© If all of the triangular faces are congruent, then all of the rectangular faces must be congruent as well.

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.
