Answer:
Step-by-step explanation:
9/16=x/12
cross product
16x=9*12
16x=108
x=108/16
simplify
x=27/4
---------------
x-3/18=12/9
x=12/9+3/18
x=24/18+3/18
x=27/18
x=3/2
--------------------
7/11=18/x+1
18/x=7/11-1
18/x=7/11-11/11
18/x=-4/11
x=18/(-4/11)=(18/1)(-11/4)=-198/4=-99/2
x=-99/2
Answer:
D
Step-by-step explanation:
It's a quartic trinomial because its has a fourth degree variable in the expression and only 3 variables in the equation.
2x⁴ - x + 5.
Linear trinomials have 1 degree 3 variables in the monomial. Eg x + y + 2 = 0 is an example of a linear trinomial.
Cubic trinomials have 3 degree and 3 variables in the equation eg = 5x³ + 2x + 1 = 0
Quadratic trinomials is the most common trinomial we deal with everyday eg Ax² + bx + c = 0
Answer: Obtuse triangle.
Step-by-step explanation:
1. By definition, you have:
- If the square of the length of the longest side is greater than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "obtuse".
- If the square of the length of the longest side is less than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "acute".
- If the square of the length of the longest side and the lenght of the other two sides are equal, then it is a right triangle.
2. Based on this information, you have:


3. The longest side is greater than the other two sides. therefore, it is an obtuse triangle.
