Answer: 1298 square feet
------------------------------------------------------
Work Shown:
Area of Rectangle on the Left = length*width = c*d = 24*20 = 480
Area of Rectangle in the center = length*width = c*b = 24*10 = 240
Area of Rectangle on the Right = length*width = c*e = 24*17 = 408
Area of top triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Area of bottom triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Add up the individual areas to get:
480+240+408+85+85 = 1298
The units are in square feet since this is dealing with area.
X^2 - y^2 = a
2xy = b
x^2 + y^2 = c
A polynomial identity is an equation that is always true.`1
You can relate x^2 + y^2 with x^2 - y^2 and 2xy in this ways.
1) Step 1:
[x^2 + y^2]^2 = x^4 + 2(xy)^2 + y^4 = c^2
2) Step 2:
[x^2 - y^2] = x^4 - 2(xy)^2 + y^2 = a^2
(2xy)^2 = 4(xy)^2 = b^2
x^4 - 2(xy)^2 + y^2 + (2xy)^2 = x^4 + 2(xy)^2 + y^2

a^2 b^2 = c^2
Answer: the identity is
c^2 = a^2 + b^2 equivalent to
(x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2
Answer:
13x
Step-by-step explanation:
The product of 13 and x would be 13*x or just simply 13x.
I need help in this one too
