Use PEMDAS
6X4=24 so you get rid of 6 and 4 and you get (24 - 4 + 9 -3)=26
Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula
Step-by-step explanation:
Sorry I had to upload a question
Plan A = 50 + 0.05(x-500)
Plan b = 20 + 0.06 (x-200)
set A equal to B
50 + 0.05 (x-500) = 20 + 0.06(x-200)
50 + 0.05x - 25 = 20 + 0.06x -12
rearrange like terms on one side.
50 - 25 -20 +12 =0.06x -0.05x
17 = 0.01x
x = 1700 minutes.
Answer:
--9x^3+12x^2-x-2
Step-by-step explanation:
(2-3x)(3x^2-2x-1)
6x^2-4x-2-9x^3+6x^2+3x
-9x^3+6x^2+6x^2+3x-4x-2
-9x^3+12x^2-x-2
