<h3>Answer :</h3>

$\bf (x+y)^2(x-y)^2$

==============

<h3>Solving Steps:</h3>

===============

$\rightarrow \sf x^4-2x^2y^2+y^4$

<u>breakdown</u>

$\rightarrow \sf x^4-x^2y^2-x^2y^2+y^4$

<u>factor common term</u>

$\rightarrow \sf x^2(x^2-y^2)-y^2(x^2-y^2)$

<u>collect in groups</u>

$\rightarrow \sf (x^2-y^2)(x^2-y^2)$

<u>apply difference between two square method:</u> x² - y² = (x+ y)(x-y)

$\rightarrow \sf (x+y)(x-y) (x+y)(x-y)$

<u>simplify</u>

$\rightarrow \sf (x+y)^2(x-y)^2$

alexgriva [62]

A = pi times radius squared (radius is half the 16 inch diameter so 8 inches)

A = 3.14 x r^2

A = 3.14 x 8^2

A - 200.96 sq inches

Find the value of x. If your answer is not a whole, leave it in the simplest radical form

Anestetic [448]

That line means the other side is also x

remember pythagoran theorem
for legs length a and b and hypootnuse length c
a²+b²=c²

so

legs aer x and x
hyptonuse is 6

x²+x²=6²
2x²=36
divide both sides by 2
x²=18
sqrt both sides
x=(√9)(√2)
x=3√2

What is the slope of the line that passes through (-3,1) and (6,-11)

tatuchka [14]

Slope: (y2-y1)/(x2-x1)
(-11-1)/(6-(-3)) = -12/9 = -4/3
The slope is -4/3
