Answer: V = (1/3)a2h.
Step-by-step explanation: Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid
9x - 4(x - 2) =x + 20
We move all terms to the left:
- 9x -4(x - 2) - (x + 20) = 0
Multiply
- 9x - 4x -(x + 20) + 8 = 0
We get rid of the parentheses.
We add all the numbers and all the variables.
We move all terms containing x to the left hand side, all other terms to the right hand side
The figures are similar.
the side that is 16 on A is similar to the side that measures 4 on figure B
24 is similar to 6
32 is similar to 8
24 is 4 times 6
24 / 6 = 4
32 is 4 times 8
32 / 4 = 4
and 16 is 4 times 4
16 /4 =4
Figure A is 4 times bigger than Figure B. That is your scale factor.
7. (6/8)
8. (2/10)
10. (4/12)
11. (4/8)
13. (10/12)
14. (6/12)
16. (9/12)
17. (5/10)
