I need a check so just want some help

bazaltina [42]

Answer and Step-by-step explanation:

We are told that AB is equal to 3x + 1.

BC is then half of AB, or $\frac{3x+1}{2}$ .

AC is then 4 less than BC, or $(\frac{3x+1}{2} ) - 4$

To find the perimeter, we add all of these together.

3x + 3x/2 + 3x/2 = 6x

1 + 1/2 + (1/2 - 4) = -2

The final answer is 6x - 2.

using percentage multipliers you just have to do:

add 0.25 to 1 because that will make 125%

then multiply it by 450ml

450ml x 1.25 = 562.5ml
