Represent the unknowns.
<span>Let x = length </span>
<span>since the width is 3/4 of the length, </span>
<span>Let (3/4)x = width </span>
<span>Recall that the area of rectangle is just width multiplied by the length, </span>
<span>A = w * l </span>
<span>Substituting, </span>
<span>432 = (3/4)x * x </span>
<span>432 = (3/4)x^2 </span>
<span>432 * 4/3 = x^2 </span>
<span>576 = x^2 </span>
<span>Get the square root of both sides, </span>
<span>x = 24 feet (length) </span>
now heres a step by step explanation Step-by-step explanation: your welcome
Multiple factor product divisor and dividend
Answer:
x > -3/7
Step-by-step explanation:
Eliminate parentheses, collect terms, and subtract the constant on the left.
5(3 -x) -4(2 -3x) > 4
15 -5x -8 +12x > 4
7x +7 > 4
7x > -3
x > -3/7 . . . . . divide by the coefficient of x
