Mark rolled a fair cube once and spun a spinner one time which is equally divided into 4 sections and contains the letters A, B, C, and D. One letter is written in each section. What his the probability that the cube will land on the number 5 and the spinner will stop on the letter C?

b.an increase in a causes b to decrease

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
