Karin is also in mr. whittaker’s science class, and she recorded the variation in water level at a different part of the river. karin observed that the water level there fell 1.68 millimeters per year for 1.5 years. which expression shows a way to use the distributive property to solve for the total variation in water level at this part of the river? 1.5(-1) + 0.68 1 + (0.)(0.68) (-1.68)(1) + (-1.68)(0.5) 1(-1) + 0.5(-0.68)

The answere is C.(-1.68)(1) + (-1.68)(0.5)

Step-by-step explanation:

Just did it

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

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
