Which polynomial is twice the sum of 4x^2-x+1 and -6x^2+x-4

-4x^2 - 6

When you add them together it gives a sum of -2x^2 - 6. Multiplying that by 2 gives you the above answer.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
