Answer:

Age of Jorge is 13 years and his brother is 12 years.

Step-by-step explanation:

Jorge is one year younger than his brother.

The sum of their ages is no less than 25 years.

Let the age of Jorge be x

Therefore, age of Jorge's brother = (x-1)

x + (x-1) > 25

2x - 1 > 25

2x > 25 + 1

2x > 26

x > 13

His brother = 13 - 1 = 12 years

Age of Jorge is 13 years and his brother is 12 years.

-3x^{2}-21x-54 what are the zeros? (Solutions)
Irina-Kira [14]
The only way to solve if it is equal to something
assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54

remember if we can do
xy=0 then assume x and y=0

so factor

0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is

if you have
ax^2+bx+c=0 then
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

x^2+7x+18
a=1
b=7
c=18

x=\frac{-7+/- \sqrt{7^{2}-4(1)(18)} }{2(1)}
x=\frac{-7+/- \sqrt{49-72} }{2}
x=\frac{-7+/- \sqrt{-23} }{2}
i=√-1
x=\frac{-7+/- i\sqrt{23} }{2}



the zerose would be
x=\frac{-7+ i\sqrt{23} }{2} or \frac{-7- i\sqrt{23} }{2}
