<span>difference of squares formula:
</span>a^2<span> – b^</span>2<span> = (a + b)(a – b)
</span>so answers are
<span>(3 + xz)(–3 + xz)
</span><span>(y2 – xy)(y2 + xy)
</span><span>(64y2 + x2)(–x2 + 64y2)
</span><span>
cause
</span><span>(3 + xz)(–3 + xz)
= </span><span>(xz + 3 )(xz - 3)
= x^2z^2 - 9
--------------
</span>(y^2 – xy)(y^2 + xy)
= y^4 -x^2y^2
----------
<span>(64y^2 + x^2)(–x2 + 64y^2)
=</span>(64y^2 + x2)(64 - x^2)<span>
= 64^2 y^4 - x^4</span>
Answer:
A. Use the distributive property.
Step-by-step explanation:
We cannot use the distribute property because there are not parentheses to distribute a number through.
5x + 15 + 2x = 24 + 4x
We can collect the terms, and isolate the variable
Answer:
Step-by-step explanation:
The equations x+5x=16
and x+5x+25=16
No, the equations are not equal. In order for an equation to be equal the equation x+5x=16 contains 25 less than the second equation.
Answer:
40cm
Step-by-step explanation:
if the area is 100 then you have to do the square root of 100 which is 10.
each side is 10.
10 x 4 because 4 equal sides
40
