Find the sum of - 3x^2 + 5x – 8 and -10x^2 – X – 3.

-13x^2+4x-11

Step-by-step explanation:

-3x^2+5x-8+(-10x^2-x-3)=?

-3x^2+5x-8-10x^2-x-3=?

(combine like terms); -13x^2+4x-11

So, your answer is -13x^2+4x-11

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
