Considering the area of the right triangle, it is found that Salome used a scale factor of 1/2 to go from triangle R to triangle T.
<h3>What is the area of a right triangle?</h3>
The area of a right triangle is given by half the multiplication of the lengths of it's sides.
In this figure, we have that the sides have lengths of 4 and 5 units, hence the area is given by:
A = 0.5 x 4 x 5 = 10 square units.
The area is one fourth of the area of triangle R. Since we are dealing with an area, that works in squared units, the scale factor is given by:
S = sqrt(1/4) = 1/2.
Hence Salome used a scale factor of 1/2 to go from triangle R to triangle T.

Answer:
90 Cookies
Step-by-step explanation:
4.50 ÷ .05 = 90
I think the equation is formed wrong, as there is no point in having x-4=x-2 twice.
It has no solution.
Answer:
3. 0
4. n = -2
Step-by-step explanation:
I haven't taken pre-calc but this looks a lot like algebra.
For #3, just plug in -2 for the x values, so:
x^2 + 4x +4
(-2)^2 + 4(-2) + 4
= 4 - 8 + 4
= 0
For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):
5n + 6 = -3n - 10
add 3n to both sides
8n + 6 = -10
subtract 6 from both sides
8n = -16
divide both sides by 8
n = -2
