Answer:
x^2+16x+64=(x+8)^2
Step-by-step explanation:
For the first spot you find the perfect square of the equation
This is found by doing (1/2 16)^2
1/2 16 = 8
8^2 = 64
The second spot is factoring, where you would put half of 16 or the square root of 64
1/2 16 = 8
root 64 = 8
A quarter means 25%, there are three quarters meaning 75%
next do 75 percent of 4

1. 2x
2. (230-x)
Step-by-step explanation:
<u>Step 1 </u>:
- If 'x' represents the feet distance that has been covered since Brian started walking towards Maggie then the expression can be given as,
= 2x
Since the distance is covered by 2 walkers and hence the total distance will be 2x
<u>Step 2</u> :
- The distance in feet between Maggie and Brian is given to be 230 ft and hence the distance in feet is given by the expression,
= (230-x)
(230 - x) is the distance covered in feet.

Answer:
52 green, 15 orange
Step-by-step explanation:
g + o = 67 g = green, o = orange, x = total
g = 3o + 7
use substitution: (3o + 7) + o = 67
solve for o:
4o + 7 = 67
4o = 60
o = 60/4 = 15
solve for g:
g + 15 = 67
g = 52
