Answer:
g=3
Step-by-step explanation:
multiply x with x-4 and +7 with x-4 to open the brackets
x^2 - 4x + 7x - 28 = x^2 +gx - 28
x^2 + 3x - 28 = x^2 + gx -28
x^2 - x^2 + 3x -28 + 28 = gx
gx is kept alone on the other side because we have to find value of g
cancel out +x^2 -x^2 and +28 -28
we ll be left with
3x = gx
divide both sides by x
3x/x = gx/x
cancel out x in the numerators with the x in the denominators
3 = g
Answer:
D. 16

Average rate of change:
Simply plug in 6 for <em>a</em> and 2 for <em>b</em>
<em />
The correct answer is 136 miles
x = 6.8×10/0.5
x = 68/0.5
x = 136 miles
Answer:
m+p/2=n
Step-by-step explanation:
You can't get any other multiplication factor, so the only way is to isolate n, by adding p to m and dividing by 2
So on the left, you reduce by 5, on the right you reduce by 7.
65/25 = 13/5
91/35 = 13/5
13/5 =13/5 ✓
