During a drought the local lake was 2 43 feet below normal levels. Two weeks
later, the water level dropped an
additional 1 3/4 feet. A month later there
was some rain that allowed the lake to
rise 12 a foot. What was the total change
in the water level of the lake?

sorry, i can't understand your question. will later if you describe more clearly!

: )

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

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
