Answer:
We call x the number of children and y the number of adults
We have system of equations
x + y = 218 (1)
1.25x + 2y = 349.75 (2)
(1) => x = 218 - y. Replace x in (2) 1.25 (218-y) + 2y = 349.75
=> y = 103 replace y in (1) x = 218-103 = 115

A rectangle has area x3 + 3x2 - 18x in.2 and width x + 6 in. What is the length in inches?
Answer:
HOPE THIS HELPS
Step-by-step explanation:
The area = length * Width.
We know the width = X+6 inches and Area = x^3+3x^2–18x.
This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.
So the length is x^2–3x inches.
The length of the rectangle is [tex]\rm x(x-3)[/tex].
Given
The area of the rectangle = [tex]\rm x^3+3x^2-18x[/tex] square inches
The width of the rectangle = x + 6 inches
Area of the rectangleThe area of the rectangle is equal to the product of length and width of the rectangle.
Let the length of the rectangle be L.
The area of the rectangle is given by;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\\rm x^3+3x^2-18x= L \times (x+6)\\\\L=\dfrac{ x^3+3x^2-18x}{x+6}\\\\L = \dfrac{ x(x+6)(x-3)}{x+6}\\\\ L = x (x-3)[/tex]
Hence, the length of the rectangle is [tex]\rm x(x-3)[/tex].

Answer:
448=h
Step-by-step explanation:
512 - h = 16 x 2²
512 - h = 16 x 4
512 -h = 64
then subtract 512 from both sides
-h = -448
two negatives equal a positive
h=448

What does "rationalizing" the denominator mean?
Answer:
It simply means getting rid of the square root or radical in the denominator
Step-by-step explanation:
Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.
For example if we want to rationalize the denominator in; 3/√2
We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.
Thus;
(3/√2) × (√2)/(√2)
This gives;
(3√2)2
Answer:
"To rationalize the denominator means to eliminate any radical expressions in the denominator such as square roots and cube roots." It is done usually by multiplying both numerator and denominator by the radical expression or another expression including the radical to be eliminated.
