Answer:
2
Step-by-step explanation:
Answer:
37 in (to the nearest inch)
Step-by-step explanation:
Assume the TV is rectangular ⇒ each corner is a right angle.
We need to find the length of the diagonal, so we can use Pythagoras' Theorem a² + b² = c² where a and b are the legs and c is the hypotenuse (diagonal) side of a right angled triangle.
In this diagram, a and b are the height and width, and the diagonal (c) is the hypotenuse.
Therefore, if a = 18 and b = 32 then:
18² + 32² = c²
324 + 1024 = c²
c² = 1348
c = √(1348)
c = 36.7151195...
c = 37 (rounding up to the nearest integer)
Therefore, the diagonal distance is 37 in (to the nearest inch)
Answer:
7.2 m²
Step-by-step explanation:
The area of a triangle is Bh/2
The diagram may fool you but its just 3*4.8/2 because the base is 3 and height is 4.8
so 14.4/2= 7.2 m²
Solution for 3n-2=15+3n equation:
Simplifying
3n + -2 = 15 + 3n
Reorder the terms:
-2 + 3n = 15 + 3n
Add '-3n' to each side of the equation.
-2 + 3n + -3n = 15 + 3n + -3n
Combine like terms: 3n + -3n = 0
-2 + 0 = 15 + 3n + -3n
-2 = 15 + 3n + -3n
Combine like terms: 3n + -3n = 0
-2 = 15 + 0
-2 = 15
Solving
-2 = 15
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
