A pyramid art installation has a surface area of 24 2. An artist creates replicas with scale factors of 1/8, 1/10, and 1/12. What is the surface area of each replica?

Match each scale factor with its correct surface area.

1. scale factor of 1/8

2. scale factor of 1/10

3. scale factor of 1/12

0.38 m^2
0.20 m^2
2.40 m^2
0.17 m^2
0.33 m^2
3.00 m^2
0.24 m^2

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
