Three hens can lay 3 eggs in 3 days. a in how many days can 7 hens lay 7 eggs?

3 days obviously

Step-by-step explanation:

From statement one, you know that it takes 3 days for a hen to a egg, so it would take 3 days for each hen to lay an egg

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

answer: sorry i can't you.
