Answer:

799

Step-by-step explanation:

Let x = the hundreds digit

Let y = the ones digit

x = y-2

We want to maximize x and y. The both have to be single digit numbers

Rewriting this

x+2 =y

The largest x can be is 7 if y is a single digit

x is 7 and y is 9

We can pick the tens digit. Make it as big as possible to make out number as large as possible

799

Use each digits 2,3,7,8 to make numbers FROM 20,21,22 SO ON ALL THE WAY TO 50 FOR EXAMPLE 2+3+7+8=20

Ahat [919]

2+3+7+8=20

2 x 3+7+ 8= 21

2 x 7 + 3+ 8= 25

8 x 2 + 7 + 3= 26

3 x 7 +8 - 2= 27

8 x 3 + 7 - 2= 29

8 x 7 ÷ 2 + 3= 31

7 x 2 x 3 -8 = 34

There is a couple, but i am not doing all of them

Solve x2 + 2x + 9 = 0

Keith_Richards [23]

$x^2+2x+9=0 \\ \\
a=1 \\ b=2 \\ c=9 \\ b^2-4ac=2^2-4 \times 1 \times 9=4-36=-32 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-2 \pm \sqrt{-32}}{2 \times 1}=\frac{-2 \pm \sqrt{-16 \times 2}}{2}=\frac{-2 \pm 4i\sqrt{2}}{2}=-1 \pm 2i\sqrt{2}$

The answer is D.
