Answer:
(c)
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° = 
= 
Multiply both sides by 12
12 × cos42° = x, hence
x ≈ 8.9 → (c)
Answer: The answer is Yes. A square is a rectangle because it possesses all the properties of a rectangle. These properties are: Interior angles measure 90∘ each.
Explanation:
Definition of a Rectangle:
A 4-sided flat shape with straight sides where all interior angles are right angles (90°).
Also, opposite sides are parallel and of equal length.
Definition of a Square:
A 4-sided flat shape with straight sides where all interior angles are right angles (90°).
Also, all sides have equal length
As you can see the first part of the definition of a square and rectangle are the same.
However, a square is a special case of a rectangle.
When all 4 sides of a rectangle are equal then the rectangle is a square.
So, a rectangle can also sometimes be a square.

Answer:
(x-2), (x+2), (3x-5)
Step-by-step explanation:
Factors of 3: ±1, ±3
Factors of 20: ±1, ±2, ±4, ±5, ±10, ±20
Possible factors of the polynomial: ±1, ±2, ±3, ±4, ±5, ±10, ±20, .... (there's a lot more but you probably do not need to list them all)
Pick a number to divide the polynomial by (I picked 2)
(3x³-5x²-12x+20)÷(x-2) = 3x²+x-10
So (x-2) is a factor of f(x) = 3x³-5x²-12x+20
Factor 3x²+x-10 = (3x-5)(x-2) these are the other factors of f(x) = 3x³-5x²-12x+20

Answer:
x=1332.5
Step-by-step explanation:
24x=(26)(1230)
24x=31980
divide both sides by 24
x=1332.5
