Let's solve your equation step-by-step.
x2−4x+3=0
Step 1: Factor left side of equation.
(x−1)(x−3)=0
Step 2: Set factors equal to 0.
x-1=0 or x-3=0
For this one add one on both sides
x−1+1=0+1 x=1
For this one add 3 on both sides
x−3+3=0+3. x=3
x=1 or x=3
Multiply both sides by 3 to get:
3r = sqrt(A)
Square both sides:
9r^2 = A
The equation you would use would be (1/8)*200 which equals 25. To get this answer you multiply the volume by the quantity of cubes.
400+30+7. +0+4
3,000,000+500+40+3,000+2+1
