The correct answer is 50 degrees
Let the first number be x
The second number is x + 2
The third number is x + 4
x + x + 2 + x + 4 = 270
3x = 270 - 6
x = 88
x is not prime so there is no first number!

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
Answer:
g(x) = 2|x|
h(x) =
|x|
Step-by-step explanation:
If you have g(x)=2f(x) and h(x)=
f(x), you can rewrite the expressions in terms of |x| as the following:
- For g(x)=2f(x) you have:
g(x) = 2|x|
-For h(x)=
f(x), you have:
h(x) =
|x|
