Answer:
The length of the rectangle is of 9 units.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
Area of a rectangle:
A rectangle has width 
and length 
. The area is the multiplication of these measures, that is:
The length of a rectangle is the sum of the width and one.
This means that 
, or 
The area direct angle 72 units. What’s the length, in units, of the rectangle
We want to find the length. So
Quadratic equation with 
. So
Since the length is a positive measure, the length of the rectangle is of 9 units.
Flip 33/5
3/5 times 5/33
3 times 5 /5 times 33

3/4 = x / 340....3 to 4 students = x to 340 students
cross multiply
(4)(x) = (3)(340)
4x = 1020
x = 1020/4
x = 255 <==
or this way.....
3 out of 4 students.....3/4 = 75%
so 75% of 340 = 0.75(340) = 255 <=
Answer:
27
Step-by-step explanation
14 is the radius so multiply by pi to get 87.96
then turn 200 fee into in which is 2400in
and divide 2400 by 87.96
Answer:
5x-6y-12=0
Step-by-step explanation:
...make y the subject y=-6/5x +2
...use the coefficient of x as the gradient,m=-6/5
...for a perpendicular line,find the negative reciprocal of the gradient,5/6
...sub into the eqn y= -1/m(x-a)+b
