The area and the ratio of the length to the width of a rectangle are given. Find the length and width of the rectangle. Area: 29
4 yd^2 l:w=3:2
1 answer:
Answer:
Step-by-step explanation:
L = 3x
w = 2x
Area = 294 ft^2
Formula
Area = L * w
Solution
Area = L * w Substitute into formula
294 - 3x * 2x Combine the right and switch
6x^2 = 294 Divide by 6
x^2 = 294/6
x^2 = 49 Take the square root of both sides
√x^2 = √49
x = 7
w = 2*7 = 2x = 14
L = 3*7 = 3x =21

796.300 because the 1 is less than four so it becomes a zero and the numbers in front stay the same.
K is 23.
As for the equation, it is
29=k+6
To solve, subtract 6 from both sides.
She should have
nickles: 6 . =30
dimes: 30 . = 300
=330 . or $3.30
According to this, then:
6x = 2*sqrt(c)*x
6 = 2*sqrt(c)
3 = sqrt(c)
c = 3^2 = 9
Hope this helps!
