So you have to start by distributing the -2 and the 4 so the equation would look like this
-2x+6-8x+32
Next you would add the like values so
10x+38
So the answer would be

10x+38

here is your answer mate.

in triangle ABC

angle ABC + angleBAC + angleACB = 180 Degrees. (angle sum property of triangle)

90 + 58 + angle ACB = 180 degree.

148 + angle ACB = 180 degree.

angle ACB = 180 - 148

angle ACB = 32 degree

the angle of elevation is 32 degrees

Solve the equation 2p/3-12=-2
-BARSIC- [3]
Hey there! 

\frac{2p}{3} - 12 = -2

Firstly, we are going add 12 on each of the sides that we're working with. like ↓ 

p - 12 + 12 \\ \\ = -2 + 12

This gives us \frac{2}{3}p = 10 (if you are wondering how we got the out come of 10 it is because I added -2 + 12 = 10

Now multiply \frac{3}{2} on each of your sides 

\frac{3}{2} ( \frac{2}{3}p)  \\ \\  =  \frac{3}{2} (10)

Cancel the first set and you will find the value of p

p = 15

Good luck on your assignment and enjoy your day

Rooms are 3 dimentional

area times height=volume

if dimentions are the same, that means that the legnth, width, height are same, so therefor they have same area (Judy is correct)

if area area same, then the height could be different, so Mrs. Ferguson is wrong





Judy is correct and Mrs. Ferguson is wrong
