If $2.35 is the unit rate, the estimated one is $2.40 if it is to the nearest tenth, $1.00 to the nearest ones. I may be wrong.
The two terms are x and 2, thus, x+2 is a binomial. We have to multiply the binomial by itself four times since it is raised to 4th power.
Let us multiply x+2 by itself using Polynomial Multiplication:
(x+2)(x+2) = x^2 + 4x + 4
Taking the result, let us multiply it again by a+b:
(x^2 + 4x + 4)(x+2) = x^3 + 6x^2 + 12x + 8
And again:
(x^3 + 6x^2 + 12x + 8)(x+2) = x^4 + 8x^3 + 24x^2 + 32x +16
The binomial expansion of (x+2)^4 is x^4 + 8x^3 + 24x^2 + 32x +16
Answer:
The final balance is $28,366.91.
So a gain of 8366.91
Step-by-step explanation:
Let's first convert Lancy's height into inches, since it includes feet.
There are 12 inches in a foot, so let's multiply 4 by 12.
4×12=48; Add 8 inches since she is 4 feet 8 inches.
48+8= 56
She is 56 inches tall. We need to find the amount of centimeters she is in height. We can do the same thing by multiplying 56 by 2.54.
56×2.54= 142.24
She is 142.24 centimeters tall.
Answer:
x: (6,0)
y: (0,-2)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x
. To find the y intercept, substitute in 0 for x and solve for y
.
Ex -
X : 2x -6(0)=12
2x=12
2 cancels out with 2
12/2 = 6
Y: 2(0 )- 6y =12
-6y=12
negative 6 times negative 6 cancels
12/-6 = -2
