Step-by-step explanation:

We know that r(x) = 3x - 1 and s(x) = 2x + 1, and we are to find which of the given expressions in the possible answer options is equivalent to .

r(x) = 3x - 1

s(x) = 2x + 1

The ratio for r/s(x) will be equal to 3x - 1/2x + 1 and x is 6 here so substituting this value to get:

Therefore, option A is the correct answer.

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

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
