Answer:
x^7+x^6+x^5-x^4-x^3-x^2-x+1
Step-by-step explanation:
The length and width of the rectangle is 11 in and 8 in respectively.
Step-by-step explanation:
Given,
The width of a rectangle is 3 in less than the length.
The area of each congruent right angle triangle = 44 in²
To find the length and width of the rectangle.
Formula
The area of a triangle with b base and h as height =
bh
Now,
Let, the width = x and the length = x+3.
Here, for the triangle, width will be its base and length will be its height.
According to the problem,
×(x+3)×x = 44
or, 
or,
or,
+(11-8)x-88 = 0
or,
+11x-8x-88 =0
or, x(x+11)-8(x+11) = 0
or, (x+11)(x-8) = 0
So, x = 8 ( x≠-11, the length or width could no be negative)
Hence,
Width = 8 in and length = 8+3 = 11 in
Using the distributiver property which is
a(b+c)=ab+ac therefor
2(x-2)=2(x)+(2)(-2)
multiply
2x+-4
2x-4
2x-4=2x-2?
false
the answer is no

Answer:

Step-by-step explanation:

Determine the scale
The scale is calculated using the following ratio:

Substitute values for Scale and Actual Measurements

Divide ratio by 20.5


This implies that: <em>1 inch on scale represents 8 ft in actual measurement</em>
