Geoffrey and his babysitter spent 1 hour preparing dinner, 1 hour and 45 minutes playing board games, and 15 minutes making dessert. how many minutes did they spend doing these activities?

if you add both hours together you'll come up with two hours, then add 45 and 15

45+15=60minutes

60minutes=1hour

three hours.

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

29 is the correct answer
