(–c^2)^3*.15c^4
power to a power in exponents is multiply
(–c^2)^3 = (-c^ 6)
= -c^6
-c^6 *.15 c^4
when multiply exponents add the exponents , multiply the coefficients
(-1*.15)c^(6+4)
=-.15 c^(10)
For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.
1. The surface area of a cone S is S=
, where r is the radius of the base and l is the slant height.
2. The slant height l is found as follows:

4. The answer is C
Answer:
2020³-1/4041
Step-by-step explanation:
First restaurant price: 29 + 6l = x
x = final cost
l = kilo of lobster
Second restaurant price: 41 + 3l = x
We want them to be the same price, so: 29 + 6l = 41 + 3l
Subtract 3l from each side
29 + 3l = 41
Subtract 29 from both sides
3l = 12
Divide both sides by 3
l = 4
So, if she buys 4 kilograms of lobster from either place, it will cost the same.
It would cost $53.
