Ответ:
➷ I assure the question is much simpler than it seems
As the roots as -7 and -2, the values in the parenthesis when the equation was factorized would be the positive version of those
Thus:
( x + 7 ) ( x + 2 )
Simply expand:
==> x^2 + 7x + 2x + 14
Simplify:
x^2 + 9x + 14
This is your answer.
❄️➶ Hope This Helps You!
➶ Good Luck (:
➶ Have A Great Day ^-^

Ответ:
x^2 + 9x + 14 = 0.
Step-by-step explanation:
First we can write it in factor form.
As the roots are -2 and -7 the factors are (x+2) and (x+7) so we have the equation:
(x + 2)(x + 7) = 0
Now expanding, we get:
x(x + 7) + 2(x + 7) = 0
x^2 + 7x + 2x + 14 = 0
x^2 + 9x + 14 = 0 (answer).

D = 32g/8cm^3
D = 4g/cm^3
I am write the other answer is wrong. She got her numbers mixed. Mass is calculated using grams and volume is calculated using cm cubed.
