Please help me for 3, 4, and 5 please

Step-by-step explanation:

3: Possible outcomes for a coin flip; heads tails

Total possible outcomes for two coin flips 2*2=4

Out the 4 possible outcomes only 1 of them both times it land on heads

1/4

4: and 5 i dont know

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
