Answer is A
The binomial can be factored using the difference of squares formula a2-b2 = (a+b) (a-b) where a=x and b=9
(X+9) x(x-9)
Answer:

In general, to find the surface area of a prism (a shape with 2 bases) is
Area of Base*2 + Lateral Area (Lateral area = Perimeter of bases * height)
#9 Area of base= 2×1÷2=1 *2=2
Lateral area= 2+1+2.2=5.2 5.2*3=15.6
Answer=17.6
#10 Area of Base= 120*2=240
Lateral Area=500
Answer=740
#11
Area of base=8*2=16
Lateral Area= 41.4
Answer=57.4
Step-by-step explanation:
We know, 9 to the power of 2 is 81
so it will be 81x
so its 81* a/b/c/d = 27/3 to the power of a/b/c/d +2
