-5/4is left of the line and opposite is right side of line
Perpendicular to x axis means then that the euation is x=something
given
(-5,-2)
(x,y)
so x=-5 is da equation
You solve this problem via PEMDAS (Parentheses Exponents Multiplication Division Addition Subtraction.)
To start you simplify everything inside parentheses.
9+3*5+5^2
Then you simplify the exponents.
9+3*5+25
Next, you simplify the multiplication signs.
9+15+25
Then you simplify all the addition signs from left to right.
24+25

Answer:
<em><u>1408</u></em> square tiles
Step-by-step explanation:
She is basically tiling the surface area of a rectangular prism that is 24 by 16 by 8 inches long. A rectangular prism has 6 sides total. Here, the sides are:
24 by 16
24 by 16
16 by 8
16 by 8
24 by 8
24 by 8
So basically, Each length is multiplied by another length 2 times each. We need to add all of these lengths together:
(24 * 16) + (24 * 16) + (16 * 8) + (16 * 8( + (24 * 8) + (24 * 8) = (384 + 384) + (128 + 128) + (192 + 192) = 768 + 256 + 384 = 1408

Since Rosa ends up on the first floor, we'll set the equation equal to 1. We don't know Rosa's floor, so we'll set her floor as the unknown x. When she goes down, we'll subtract from her floor (x) and when she goes up, we'll add.
x= Rosa's floor
down 2= subtract 2
up 7= add 7
down 15= subtract 15
ends up on 1 so equation equals 1
x - 2 + 7 - 15= 1
combine like terms
x - 10= 1
add 10 to both sides
x= 11
ANSWER:
Rosa works on the 11th floor
Hope this helps! :)
