Part A: 3x + 15 = 5x - 25
Part B: x = 20
X(exponent 2) - x - 6
------------------------- =
x(exponent 2) -4
(x-3)(x+2)
------------- =
(x-2)(x+2)
Cancel out the x + 2 factors.
x-3
---- <== ANSWER
x-2

Answer:
y=8
Step-by-step explanation:
We need to find the equation for the line.
The first step is to find the slope
We need 2 points (0,2) (2,3)
slope = (y2-y1)/(x2-x1)
= (3-2)/(2-0)
= 1/2
We know the y intercept ( where it crosses the y axis) at 2
Lets use the slope intercept form of the line
y= mx+b
y = 1/2 x+2
If we want to find the value of y when x =12 , substitute the value of x=12
y =1/2 * 12 +2
y = 6+2
y=8
Surface area= sum of all the areas of the shapes that cover an object
area of a one face= 4
number of faces= 37
surface area= 4×37=148
