Answer:
c. (A + B)^2-A^2 + 2AB + B^2
Step-by-step explanation:
Given that:
a.
(A-B)^2 = A^2 - 2AB + B^2
If and only if AB = BA
Then;
(A-B)^2 = (A -B ) (A - B)
(A-B)^2 = A^2 - AB-BA + B^2 (FALSE)
b.
(AB)^2=A^2B^2
on true if any only if AB =BA
(AB)^2= (AB) (AB)
c.
(A+ B)^2 = A^2 + 2AB + B^2
(A+ B)^2 = (A + B) (A+B)
(A+ B)² = A × A + A × B + B × A + B × B
(A+ B)^2 = A^2 + A*B + B*A + B^2
This is true
whats is y? I can't solve the problem without it
Answer:
x=1/4
Step-by-step explanation:
4x+5=4+2
4x+5=6 simplify
4x+5-5=6-5 subtract from both sides
4x=1 simplify
(4x/4)=1/4 divide both sides
x=1/4 final answer
When 2 tangents are joined to a circle, the tangents are of equal length so the triangle is isosceles. Then again it is possible for it to be equilateral.
Answer:
Step-by-step explanation:
The given expresion is
Observe that 4 is common to 8,-24, and 4
Observe also that, m²n is common to all the terms.
Hence the GCF is:4m²n
We factor the GCF to get;
