Answer:
The expressions which equivalent to 
are:
⇒ B
⇒ C
Step-by-step explanation:
Let us revise some rules of exponent
Now let us find the equivalent expressions of
A.
∵ 4 = 2 × 2
∴ 4 = 
∴ 
= 
- By using the second rule above multiply 2 and (n + 2)
∵ 2(n + 2) = 2n + 4
∴ = 
B.
∵ 4 = 2 × 2
∴ 4 = 2²
∴ = 2² × 
- By using the first rule rule add the exponents of 2
∵ 2 + n + 1 = n + 3
∴ =
C.
∵ 8 = 2 × 2 × 2
∴ 8 = 2³
∴ = 2³ × 
- By using the first rule rule add the exponents of 2
∵ 3 + n = n + 3
∴ =
D.
∵ 16 = 2 × 2 × 2 × 2
∴ 16 = 
∴ 
= ×
- By using the first rule rule add the exponents of 2
∵ 4 + n = n + 4
∴ = 
E.
is in its simplest form
The expressions which equivalent to are:

Answer:
Step-by-step explanation:
if (h,k) is the center and r be radius of circle.
Then eq. of circle is (x-h)^2+(y-k)^2=r^2
reqd. eq. of circle is (x+4)²+(y+5)²=(√6)²
or (x+4)²+(y+5)²=6
We have the points (1, -6) , (2, -12)
Find the slope (m)
m = (y₂-y₁) / (x₂-x₁)
Plug in the values.
m = (-12 + 6) / (2 - 1)
Simplify.
m = -6/1
So, our slope is : m = -6
We are looking for our equation in point-slope form.
Point-slope form : y - y₁ = m(x - x₁)
Simply plug in everything.
Our given points : (1, -6) and (2, -12)
y - (-6) = -6(x - 1)
Simplify.
y + 6 = -6x + 6
Subtract 6 from both sides.
y = -6x + 6 - 6
Simplify.
So, y = -6x
Your answer is C) y = -6x

Answer: -2x
X being how tall each level is
If you don't have that information it would just be
