option d
Part 3:
Multiply through by the LCM of 2 and 3 (i.e. 6)
option b
Part 4
x^2-3x-8=x+4
option d
Part 5
Joseph is solving the equation x^2+8x-4=0 using the technique completing the square.
x^2+8x-4=0
x^2+8x+?=4+?
In completeing the square method, you divide the coeficient of x by 2, square the result and add to both sides of the equation.
Therefore, he should add 16 to both sides because (8/2)^2=16.

Answer:
The fraction of tiles that will be the color of "sand" is 23/60
Step-by-step explanation:
we know that
The sum of the fractions of the tiles must be equal to 1
Let
x ----> the fraction of tiles that will be the color of "sand"
we have that
solve for x
Find the Least Common Multiple of denominators
Multiply both sides by 60
simplify
therefore
The fraction of tiles that will be the color of "sand" is 23/60
