Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
Answer:
$1620
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the length of the side )
Here V = 5832 , then
s³ = 5832 ( take cube root of both sides )
s =
= 18 ft
The area of the square floor is then
area = 18² = 324 ft²
cost = 324 × $5 = $1620
I had the same thing to do :) im doing mine now, if needed just pm me and ill help more, just right about the proposes you see
Answer:
<h2>2¹²</h2>
Step-by-step explanation:
The sum of the coefficients in the expansion of (x+1)^12:
= 12C0 + 12C1 + 12C2 + . . . + 12C11 + 12C12
the formula says that this sum equal to 2¹².
Other examples
The sum of the coefficients in the expansion of (x+1)^3:
3C0+3C1+3C2+3C3
=8 = 2³
The sum of the coefficients in the expansion of (x+1)^4:
4C0+4C1+4C2+4C3+4C4
=16 = 2⁴
