Answer:
x= 5
Step-by-step explanation:
We are given;
- Base of the triangle as x
- Length of the leg is 4x-5
- An isosceles triangle has two equal legs and a base.
- The perimeter of the triangle is 35 (spelling mistake in the question)
To get the perimeter of a triangle we add the lengths of all sides of the triangle.
Therefore;
x + 4x-5 + 4x-5 = 35
9x - 10 = 35
9x = 45
x = 5
Thus, the value of x is 5
I worked this out based on what I know hope it’s the right answer to
Both expression have the same denominator: 9x²-1. Thus it must not be 0.
9x²-1=(3x-1)(3x+1)=0, resulting x=+-1/3.
Restrictions: x in R\{-1/3, 1/3}
Adding those expressions:
E=(-x-2)/(9x²-1 ) + (-5x+4)/(9x²-1)=
(-x-2-5x+4)/(9x²-1)=(-6x+2)/(9x²-1)=
(-2)(3x-1)/(9x²-1)=-2/(3x+1)
E=-2/(3x+1)
Answer:
Pretty sure it's B!
Step-by-step explanation:
Over the Y axis- (2,1)
To the left two times= (0,1)
