Step-by-step explanation:
The unit rate would be how many eggs one chicken lays
To do this, you would create a ratio
30:12 = x:1
30 = 12x cross multiply
30/12 = 12x/12 isolate the variable
2.5 = x
The unit rate is 2.5:1 or 
:1

Y=x²+8x+14
to make a square, if a is 1, add (half of b)²
in this case, a=1, b=8, half of 8 is 4
y=x²+8x+4²-4²+14
y=(x+4)²-16+14
y=(x+4)²-2
B is the answer.
another way to do it:
the vertex is at x=-b/2a=-8/2*1=-4
when x=-4, y=(-4)²+8(-4)+14=-2
so the equation is y=[x-(-4)]²-2, which is y=(x+4)²-2, the same answer B
The question is really quite easy. You just have to find the distance between the sea level and the point down the water. Make an illustration about the problem to visualize it better. The picture is shown in the attached picture. The distance we want to get is denoted as x. The solution is as follows:
x = 4.7 - 0.5 = 4.2 m
Hope this helps!
Left side angle = 180-150-12 = 18 degrees
10 / sin 12 = c / sin 18
c = 10 * sin 18 / sin 12
c = 14.9 cm to nearest tenth
Answer:
40x-24
3b(6c-3a+c)
Step-by-step explanation:
For the first one use distributive property and multiply each term by 8.
For the second one find a common factor which is 3b and divide all terms by that number.
