Answer:
Step-by-step explanation:
Difference = New temperature - original temperature
= -12 - (18)
= - 30
New temperature is 30° less than the original temperature
It is the right answer........
The value of 
is 4.
By Geometry, we know that line segment 
, which is equivalent to:
(1)
Now we solve algebraically the resulting expression.
If we know that 
, then we solve the equation for :
The value of is 4.

Side 1 = short side = 2x-3
side 2 = longer side = (short side) + 6 = (2x-3)+6 = 2x+3
side 3 = side 2 = 2x+3
Side 2 and side 3 are the longer two congruent sides
Add up the three sides and set them equal to the given perimeter of 33. Solve for x
(side1)+(side2)+(side3) = perimeter
(2x-3)+(2x+3)+(2x+3) = 33
(2x+2x+2x) + (-3+3+3) = 33
6x+3 = 33
6x+3-3 = 33-3
6x = 30
6x/6 = 30/6
x = 5
If x = 5, then the longer sides are 2*x+3 = 2*5+3 = 10+3 = 13 inches each
(note: the short side is 2*x-3=2*5-3=10-3 = 7 inches)
Answer: 13 inches
