Simplify this expression. <br><br> -3[2-(y-5)]-4[3(y+1)-(6-y)(-2)]
suter [353]

Answer:

-81 - y

Step-by-step explanation:

To simplify the expression -3[2-(y-5)]-4[3(y+1)-(6-y)(-2)] use order of operations or PEMDAS.

-3[2-(y-5)]-4[3(y+1)-(6-y)(-2)]

-3[2-y+5]-4[3y + 3+12 -2y]

-3[7-y] -12y-12-48+8y

-3[7-y] - 4y - 60

-21 + 3y - 4y - 60

-81 - y

If the endpoints of AB are located at (0,7) and (8,8) what is the length of AB?
Leokris [45]

Answer:

√65

Step-by-step explanation:

The distance formula can be represented as

\sqrt{(x_{2} -x_1)^2 + (y_2-y_1)^2}

Taking (8,8) as (x₂, y₂) and (0,7) as (x₁, y₁), we have

\sqrt{(8 -0)^2 + (8-7)^2}\\= \sqrt{8^2 + 1^2}\\= \sqrt{65}

as our answer
