Write a quadratic equation in standard form that has roots of -12 and 2
djyliett [7]

Answer:

x² + 10x - 24

Step-by-step explanation:

Given the roots are x = - 12 and x = 2 then the corresponding factors are

(x + 12) and (x - 2) and their product equals zero , that is

(x + 12)(x - 2) = 0 ← expand using FOIL

X² + 10X - 24 = 0

PLEASE HELP I NEED THE ANSWER ASAP PLEASE PLEASE !! ILL GIVE BRAINLIEST.
soldier1979 [14.2K]

Answer:

10 + 5i & 10 - 5i

Step-by-step explanation:

10 + 5i is still just 10 + 5i because we treat i like it's x.

Complex conjugate if I remember correctly is like a + or - form, so I believe 10 - 5i is correct?

Hope this helped.

What is the surface area?<br>What is the surface area of G​
myrzilka [38]

Answer:

226 cm^2

Step-by-step explanation:

It’s literally a rectangular prism If you put it together. The side with 2 cm and 11 cm , the surface area is 22 and since this is a rectangular prism, that means there is a second of the same kind. Then you get the larges box, since you know that the top side is 11 and the left side is 7, you multiply that * 2 which you then get 154. You add that up with the side that you solved before so 154 + 44 = 198. You then figure out the left side 7 * 2 * 2 (because there are two of them). 28 + 198 = 226 cm^2.
