Q^2 - 9 = (q + 3)(g - 3)....this is a difference of squares
Answer:
x= -8 x=2
Step-by-step explanation:
x^2 +6x - 6 = 10
Subtract 10 from each side
x^2 +6x -16 =0
Factor what 2 numbers multiply to -16 and add to 6
8*-2 = -16
8-2 = 6
(x+8) (x-2) =0
Using the zero product property
x+8 =0 x-2 =0
x= -8 x=2

Answer:
A is A=2(1+2)a2
B is A≈208.18cm²
Step-by-step explanation:
A explanation is A=2(1+2)a2=2·(1+2)·102≈482.84271
B explanation is A=145(5+25)a2=14·5·(5+2·5)·112≈208.17777cm²
