A = 1/2 (A + B)

distribute the 1/2 into the parentheses

A = 1/2A + 1/2B

Subtract 1/2A from each side

A - 1/2A = 1/2B

Combine like terms

1/2A = 1/2B

Isolate B by dividing each side by 1/2

1/2A ×2/1 = B

Multiply

2/2A = B

A = B

WHAT TERM SHOULD BE ADDED TO CREATE A PERFECT SQUARE TRINOMIAL?

boyakko [2]

Answer: We should add the constant 81 to the expression to have a perfect square trinomial.

The perfect square trinomial that would be formed would result from (x + 9)^2.

We can use foil to prove it.

(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81

81 is the value that must go with 18x in the middle to form the perfect square trinomial.

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Sindrei [870]

ANSWER

$a_{55}=161$

EXPLANATION

The general term for the sequence is

$a_n=-1+3(n-1)$

To find the 55th term, we have to substitute
$n = 55$
in to the general term and simplify.

This implies that,

$a_{55}=-1+3(55-1)$

$a_{55}=-1+3(54)$

$a_{55}=-1+162$

$a_{55}=161$

Therefore the 55th term is 161.
