Hi!to calculate a square root without a calculator is to see if you can get to that whole number by squaring smaller numbers,or multiplying a smaller number by it self.
22.
14-1.5 = 12.5
16-1.5 = 14.5
Put a dot at 12.5 and a dot at 14.5 then connect them with a line and write (1.5 added) below the graph
(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8
Answer:
7
Step-by-step explanation:
Blue beads: 100/130, which reduces to 10/13.
Red beads: 20/130, which reduces to 2/13.
You're just taking the fraction of the certain color of beads compared with the total number of beads, which is 130.
