Answer:
D
Step-by-step explanation:
EVerytime you do exponents its positive
First, set these expressions equal in an equation. solve for x, then multiply x by 3 because there are 3 sides. the perimeter is 12
Factor out a GCF of 4, then you are left with perfect squares.
4(100-9x^2)
Factor what is left as a difference of perfect squares (the outside and inside terms from FOIL should cancel out which is why each parenthesis has a different sign
f(10+3x)(10-3x)
