Answer:
a=35x−x^2
Step-by-step explanation:
Having
70 ft of fencing with a
width of x
feet and knowing the perimeter of a rectangle is
p=2w+2l
we can state the length of the garden as:
70=2x+2l
and solving for l
we know the length with be:
2l=70−2x or l=35−x
And then knowing the formula for the area of a rectangle is
a=w⋅l
we can write the equation as:
a=x⋅(35−x)a=35x−x^2
Answer:
130 degrees
Step-by-step explanation:
arc CA is 50 since the angle is 50 and then you would subtract from 180 since it is half the circle which leaves you with C, or 130 degrees.
Answer:6.36
Step-by-step explanation:
Multiply the bill($42.40) by 0.15
X=45y
x is distance and y is the time the car goes 45 miles per hour so distance equals 45 times time
