Answer:
6 + 3
or 6 - 3
Step-by-step explanation:
x^2 - 12x + 36 = 90
x^2 - 12x - 54 = 0
x = 
a = 1, b= -12, c= -54
6 + 3 or 6 - 3
x = number of packages he bought
y = number of popsicles in each package
Here are the two equations:
xy = 54
x = 3 + y
Using the substitution method, you can solve them to find x and y.
(3 + y)y = 54,
3y + y^2 = 54
y^2 + 3y - 54 = 0
Solve the quadriatic equation:
(y +9)(y - 6) = 0
y = -9, 6.
Plug y into: xy = 54
x(-9) = 54, x = -6.
x(6) = 54, x = 9.
So he bought 9 packages of popsicles, bc you can't bye -6 packages.
Answer:
Acceleration equals zero because of constant velocity
coefficient
Fr = coefficient × r
60.62= ce ×100
0.60 = coefficient
As an estimate the sum may read 720-210, which makes 510
