Step1: Find the area of the triangular lawn
Given, base of the triangle is y metres and the height is z metres
Area of the triangle =

× base × height
Therefore, area of the triangular lawn =

Step 2:Find the cost of planting the grass
Rate of planting the grass is Rs. x per square metre.
Therefore, the cost of planting the grass on a triangular lawn =cost per square meter × area of the triangular lawn
=x×

Step-by-step explanation:
Answer:
I'd go with B
Step-by-step explanation:
It contains -2 in its domain, a real number
Answer:
300 phones the company activated in one minute
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Step-by-step explanation:
Here is the correct question: Meg wants to find how many phones the company activated in one minute. Explain why meg can use 15000 divided by 50 to find the answer.
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
Therefore, in the above question Meg knew the number of total phone activated by company in 50 minutes, which is 15000.
Now, she want to find how many phones the company activates in one minute.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Phones the company activated in one minute= 
∴ 300 phones the company activated in one minute.
Find the slope of the line that will go through point (4, 5) and (8, 9) first and then you can use the point-slope form to figure out the equation of the line. Since I am not sure what form of the equation they want, I will just provide you the point-slope form, standard form, and the slope-intercept form of the line.
The slope can be calculated by subtracting the difference of the y-coordinates of the two points and then dividing it by the difference of the x-coordinates.
(y_2 - y_1) / (x_2 - x_1) = slope
(9 - 5) / (8 - 4) = 4 / 4 = 1
The point-slope form is: y - y_1 = m(x - x_1)
Let's take the coordinate (4, 5) and use 4 for x_1 and 5 for y_1.
y - 5 = 1(x - 4)
The slope-intercept form is: y = mx + b
We can modify the point-slope form to look like the slope-intercept form.
y - 5 = 1(x - 4)
y = x - 4 + 5
y = x + 1
The standard form is: ax + by = c
We can modify the slope-intercept form to look like the standard form.
y = x + 1
y - x = 1
-x + y = 1
Point-slope form: y - 5 = 1(x - 4)
Slope-intercept form: y = x + 1
Standard form: -x + y = 1
