What is perfect square trinomials
(x+4)^2=

x² + 8x + 16

Step-by-step explanation:

(x + 4)² = (x + 4)(x + 4)

Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is

x(x + 4) + 4(x + 4) ← distribute both parenthesis

= x² + 4x + 4x + 16 ← collect like terms

= x² + 8x + 16 ← perfect square trinomial

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
