Answer:
Simplified it is 
Step-by-step explanation:
The x-intercepts of a parabola form the factors of the equation. Since the x -intercepts are (-2,0) and (4,0) then the factors are (x+2) and (x-4). Factors are pieces which multiply to make the equation.
This is the standard form of the parabola 
. Since the y-intercept of the parabola is (0,4) then a number must also be multiplied to it
We find a by plugging in x=0 and y=4.
So the equation is .
When simplified it is

Answer:
I, III
Step-by-step explanation:
You know from your study of the Pythagorean theorem that a triangle with sides 3, 4, and 5 will be a right triangle. Any scaled version of this triangle will also be a right triangle, so it is helpful to learn to recognize when scaled values of these numbers are used.
I -- the scale factor for a 3-4-5 right triangle is 2/10
II -- no isosceles right triangle has integer side lengths. (not a right triangle)
III -- the scale factor for a 3-4-5 right triangle is 1/13
IV -- the lengths do not form a triangle
Triangles I and III are right triangles.
_____
<em>Additional comment</em>
The sides of an isosceles right triangle have the ratios 1 : 1 : √2. The square root of 2 is irrational. No scaled version of this triangle can have rational side lengths.
It will be the sum of any two no. Which will give ans as 180 so i will conclude 90+90
Or 90 marks in both exams
Answer: Craft Emporium(Based on what you told me)
Step-by-step explanation:
30% is the same as 30/100
Since this is $28 dollars:
100/100 - 30/100 = 70/100
28 x 70/100 = $19.60 dollars
35% is the same as 35/100
Since this is $25 dollars:
100/100 - 35/100 = 65/100
25 x 65/100 = $16.25 dollars.
