Answer: Total area  2800 sq.yards

Step-by-step explanation:

First roof  

2 rectangles       and      2    trangles

for rectangles area = b*h

then area of one rectangle = 20*30  = 600 sq.yards

We have 2 rectangles then  2 * 600 = 1200 s. yards

for triangles area 1/2 b*h

Then area of one triangle   = 0.5* 5*20  = 50 sq.yards

We have 2 triangles  then 2 * 50  = 100 sq.yards : 1300 sq.yards

Total area first roof  = 1300 sq.yards

Second roof    

Area of rectangle = b*h       = 25*60   =  1500sq.yards

Total area second roof  = 1500 sq.yards

The second question with the blank please
konstantin123 [22]
Usually called "half of base times height", the area of a triangle is given by the formula below.Area=ba2whereb  is the length of the base
a  is the length of the corresponding altitude

You can choose any side to be the base. It need not be the one drawn at the bottom of the triangle. The altitude must be the one corresponding to the base you choose. The altitude is the line perpendicular to the selected base from the opposite vertex.

In the figure above, one side has been chosen as the base and its corresponding altitude is shown.

Someone know how to do this?: 6x2+18x=0
Crazy boy [7]
The answer to the question is: Yes.

Explanation:  It can be solved by following exactly the same procedures
that solved the other two questions that you posted within the past 15 minutes.

Since I'm here already, here is the solution to this one:

6x² + 18x = 0

Divide each side of the equation by 6 :

x² + 3x = 0

Factor the left side:

x(x+ 3) = 0

This statement is true if x=0 or if x=3.

The solution to this one is even the same as the solution to the last one you posted.
You really ought to take a break, go back, review the solutions you've been given,
and try to solve a few on your own.

Ket [755]

Answer:

The value of 4 is an input of the function

Step-by-step explanation:

Let

x -----> the independent variable or input value

y ----> the dependent variable or output value

we know that

Looking at the graph

The domain (input values) of the linear function is equal to the interval

[1,∞)

x\geq 1

All real numbers greater than or equal to 1

The range (output values) of the linear function is equal to the interval

(-∞,3]

y\leq 3

All real numbers less than or equal to 3

therefore

The value of 4 is an input of the function
