Answer:
I think its (6042 = 1780 + a) but I'm not really sure though but I hope if that helped somehow
Answer:
-3
Explanation:
I’ve attached my work
Hope it helps, let me know if you have any questions !
To find the roots, we need to factorize the quadratic expression
x² + 6x - 55 = 0
x² + 11x - 5x - 55 = 0
x(x + 11) - 5x - 55 = 0
x(x + 11) -5 (x + 11) = 0
(x - 5)(x + 11) = 0
Then solve the value of x
x - 5 = 0
x = 5
or
x + 11 = 0
x = -11
The roots are -11 and 5
Sum of the roots
sum = -11 + 5
sum = -6
The answer is option b
Answer:
92
Step-by-step explanation:
1,374 ÷ 15 = 91.6
you can't have .6 of a box so you add an extra one to make 92
