x = -2

Step-by-step explanation:

x^2 - 3x - 10 when we factorize equals

(x + 2) (x - 5)

3x^2 + 5x - 2 when we factorize equals

(3x - 1) (x + 2)

x + 2 is the common term and when we put the 2 on the other side of the equation we get x = -2

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

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
