Answer:

x = -4 ± 3√6

Step-by-step explanation:

x² + 8x = 38

Complete the square by adding (8/2)² = 16 to both sides.

x² + 8x + 16 = 38 + 16

(x + 4)² = 54

x + 4 = ±√54

x = -4 ± 3√6

barxatty [35]

Answer:

155 Units

Step-by-step explanation:

Rate of Bug (given) = 11 units PER MINUTE

It never changed direction, so it was going in positive direction (assume).

In 7:15 pm (evening), it was at Point 100,

We want the point at which it was at 7:20 pm.

7:20pm - 7:15pm = 5 minutes

So, time passed 5 minutes. It's rate is 11 units PER MINUTE, so in 5 mins:

11 * 5 = 55 units

Assuming he is going in positive direction, the bug will be at:

100 + 55 = 155 Units

Please help could you explain or show work so I will remember how to do problems like this?
antiseptic1488 [7]

Answer:

x = -8

Step-by-step explanation:

4x - (x - 4) = - 20

Distribute the minus sign

4x - x +4 = -20

Combine like terms

3x+4 = -20

Subtract 4 from each side

3x+4-4 = -20-4

3x = -24

Divide by 3

3x/3 = -24/3

x = -8
