(4x-3)(2x+1) expand the brackets: 8x^2 -2x -3 = area
Answer:
c
Step-by-step explanation:
find 6%
429.99*6/100= 25.7994
Total cause of the laptop
429.99+25.7994= 455.79
Answer:
31.6%
Step-by-step explanation:
it is given that
Area of Department X = 8,000 square feet
Area of Department Y = 5,000 square feet
Area of Department Z = 6,000 square feet
now the total area = 
=
square feet
Percentage of area covered by Department Z =
%
=
%
=
%
percentage of overhead expenses applied to Department Z = percentage of area covered by Department Z
hence we have,
percentage of overhead expenses applied to Department Z = 31.6%
(3x + 4)2 = 14
(3x + 4)2 means that 2 will multiply both 3x and 4
2 * 3x = 6x 2 * 4 = 8
6x + 8 = 14
Move +8 to the other side of the equation
6x = 14 - 8 Note : Moving +8 to the other side will change the sign in front of it, that is from + to -
6x = 14 - 8
6x = 6
Divide both sides by 6 because of the 6 beside the x : 6x
6x/6 = 6/6
x = 1
The first point could be (5, 40)
The second could be (25, 20)
That's just assuming the number of minutes are the x-coordinates...
Hope this helps!
