Area of a rectangle of length L and width W is A = LW.
Here, A = 60 ft^2 = (12 ft)(2x-3 ft). Let's find the values of x for which the area =60 ft^2, and then the values of x for which the area is greater than 60 ft^2.
60 = 12(2x-3) becomes 5 = 2x - 3 after dividing both sides by 12.
Adding 3 to both sides of this last equation results in 8 = 2x, so x = 4.
Does (12 ft)(2[4 ft] - 3) = 60? Does (12 ft)(5 ft) = 60 sq ft? YES.
The area of this rectangle will be greater than 60 sq ft if x>4 ft. (answer)
The easiest way to evaluate the limit is to simply subsitute the value into the function
as x approaches -3
just subsitute -3 for x
(-3)³=(-3)(-3)(-3)=-27
answer is -27
115% of the price is 270,25
115*x/100=270,25
x=270,25*100/115
x=235 $ is the price
270,25-235= 35,25 $ is the tax
Answer:
y = -7
Step-by-step explanation:
Put x = 2 in any one of the equation
5x +2y = -4
5*2 + 2y = -4
10 +2y = -4
2y = -4 -10
2y = -14
y = -14/2
y = -7
V=π * r^2 * h/3 = π * 2^2 * 8/3 ≈ 33.51032 or about 34 units^2
