Answer: first option.
Step-by-step explanation:
The ratio of the area of the triangles can be calculated as following:
Where 
is the lenght of the given side of the smaller triangle and 
is the lenght of the given side of the larger triangle.
Therefore:
It can be written as following:
The ratio of the perimeter is:
Where is the lenght of the given side of the smaller triangle and is the lenght of the given side of the larger triangle.
Therefore:
It can be written as following:
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:
b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15
Using the values, we get:
So, the correct answer to this question are option B and D
Answer:
y = 
x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) =( 8, - 3) and (x₂, y₂ ) = (0, - 5)
m = 
= 
=
Note the line crosses the y- axis at (0, - 5 ) ⇒ c = - 5
y = x - 5 ← equation of line
Answer:
What's the question?
Step-by-step explanation:
Step-by-step explanation:
3 and 4.
because the sum of the smaller two sides of a triangle have to be less than or equal to the 3rd larger side.
