Perform the operation.
(-x^2 – 1) – (-2x^2 – 4)

Okay!

Step-by-step explanation:

I have simplified the operation, and I got x^2 + 3.

If you wanted me to evaluate, the answer is still  x^2 + 3.

If you wanted me to subtract then the answer is again,  x^2 + 3.

Basically the answer is  x^2 + 3.

Have a good day!

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

1 1/5
