Solve the quadratic by factoring.<br> x^2-5x-31=5
torisob [31]

Answer:

x =  - 4\: or \: x =  9

Step-by-step explanation:

make one side equal to zero:

{x}^{2}  - 5x - 36 = 0

find two factors that multiply to -36 and add to -5 (-9 & 4)

{x }^{2}  - 9x + 4x - 36 = 0

factorise

x(x - 9) + 4(x - 9) = 0

(x + 4)(x - 9) = 0

solve for x

x =  - 4 \: or \: x = 9

If every fourth customer gets stickers and every tenth customer gets a notebook, which customer will get both?
prisoha [69]
The 20th costumer will get both.
You have to fine the least common multiple of both numbers. So the closest those two numbers have is 20.
4 \times 5 = 20 \\ 10 \times 2 = 20
