-18+4x
2(2x-9)
4x=18
-4x=-18
x=18/4
-x=-18/4
Answer:
y = 4
Step-by-step explanation:
Since the line in question is parallel to the x axis, we can tell that going from one end of the line to the other, x value changes, but y value always stays the same and equals 4.
Among many other formulas, the area of a triangle is

where B is the angle between sides a and c.

Answer: 92.05 sq cm, first choice
Bonus. Here's a formula for the area S of a triangle your teacher doesn't know:

7x+(x-4)(X+5)-5x
7x+(X*2+ 5x-4x-20)-5x
7x+(X*2+ x-20)-5x
X*2+3x-20
Answer:
The correct answer is Kinetic Energy
Step-by-step explanation:
From conservation of energy a body at rest posses energy called Potential Energy under which it acquired at particular position of the body i.e at rest
Then as soon body starts moving with a certain speed "v" there is conservation of energy from Potential energy to Kinetic energy given as product of a half with mass of the body and square of its velocity.
In formular K.E= 1/2mv^2 where m stands for mass of the body and v is the speed of the body.
