<h3>Question:</h3>
The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x.
<h3>To find:</h3>
<h3>Given:</h3>
<h3>Answer :</h3>
<u>To</u><u> </u><u>find</u><u> </u><u> </u><u>area</u><u> </u><u>first</u><u> </u><u> </u><u>we</u><u> </u><u>should</u><u> </u><u>know</u><u> </u><u> </u><u>value</u><u> </u><u> </u><u>of</u><u> </u><u>with</u><u>.</u>
So first Let's find width by using this formula:
Insert Value of length and perimeter.
Now Let's find Area by using this formula
hope it helps!
X intercept is 2
y intercept is 4
slope is 4/2
Answer:
Since there are two identical slopes, multiply 800 by 2 to get a total roof area of 1,600 square feet. Divide the total roof area by 32 to get the number of sheets you will need to cover the roof. A typical 4 foot by 8 foot sheet of plywood covers 32 square feet.
Step-by-step explanation:
I don't know so sorry I'll let you know when I do.
Y = 3x - 1 when x = -1
When the problem tells you what x is, put it into the problem:
y = 3(-1) -1
Solve the parentheses:
y = -3 -1
Now do the rest of it:
y = -4
I hope this helped you <3
