Given, the rate of growth of St. Augustine grass is 
cm per week.
We have to find the number of weeks that the grass grow to 
cm.
Let's take the number of weeks be x.
In 1 week the grass grow = cm
So in x weeks the grass grow = 
cm
So we can write,
To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,
Now to get we will move 4 to the right side by dividing it to both sides. We will get,
So we have got the required answer.
After 3 weeks the grass grow 
.
Slope intercept form is y=mx+b
first plug in m
y=-1/2X + b
now plug in the point (8,1) for the x and the y
1=-1/2(8) + b
now you need to solve for b
simplify
1=-4+ b
add 4
5=b
now that you know b
you can plug it into the equation along with the m
so the answer is
y=-1/2X + 5
6/10 x 10/1 = 60/10
Which equals 6

helooo 28 is the answer thank you
Answer: D. A square with side length of 20 feet.
Step-by-step explanation:
To determine the side length of the square that could be connected to side b of the triangle to correctly complete the model, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Hypotenuse = side length of square C
Adjacent side = side length of square A
Let B represent the side length of the required square.
Area of square = (side length)²
Therefore,
841 = 441 + B²
B² = 841 - 441 = 400
B = √400
B = 20 ft
