Answer:
Triangle A - Scalene
Triangle B - Isosceles
Triangle C - Isosceles
Triangle D - Equilateral
Step-by-step explanation:
Scalene - No equal sides or angles
Isosceles - 2 equal sides or 2 equal angles
Equilateral - all equal sides or all equal angles

The answer is 12 scarves.
If the number N of scarves she can make is inversely proportional to the area <span>A of each scarf, then we have equation:
</span>N = x/A,
where x is the total area of the large piece of fabric she uses
First, we need to calculate what is the total area of the <span>large piece of fabric she uses (x):
It is given:
A = 4 square feet
N = 15
If </span>N = x/A, then: <span>x = A * N = 4 * 15 = 60 square feet
Now, we have to calculate the number of scarves she can make if the area of the scarf is 5 square feet.
So, it is given:
x = 60 square feet,
A = 5 square feet
</span>If <span>N = x/A, then: N = 60/5 = 12 scarves </span>
Answer:
It is very difficult to know because you did not include the function g(x), you only gave us f(x).
Given two lists of ordered pairs [x,f(x)] and [x,g(x)]. If for every ordered pair on the f(x) list the reverse is on the g(x) list the functions are inverses.
f(0) = 5 so for (0,5) on the f(x) list then (5,0) must be on the g(x) list
f(1) = 7 so for (1,7) on the f(x) list then (7,1) must be on the g(x) list
f(2) = 9 so for (2,9) on the f(x) list then (9,2) must be on the g(x) list
So even though you didn’t list g(x), g(x) = (x/2) - 5/2
X^2+7x-18=0
x^2+9x-2x-18=0 ( splitting middle term)
x(X+9)-2(x+9)=0
(x-2) * (X+9) =0
Therefore, X=+2 or -9
