Joelle made 3 bracelets in 15 minutes, 4 bracelets in 20 minuets, and 6 bracelets in 30 minutes. is the relationship between the number of bracelets and time a proportional relationship? if so, what is the unit rate?

45

step-by-step explanation:

30+15

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
