Given:
Point F,G,H are midpoints of the sides of the triangle CDE.
To find:
The perimeter of the triangle CDE.
Solution:
According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.
FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get
GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get
Now, the perimeter of the triangle CDE is:
Therefore, the perimeter of the triangle CDE is 56 units.
Answer:
A.
Step-by-step explanation:
It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not.
Hi. 2 (×+1)=3×-1 ; 2x+2= 3x-1 ;
2x-3x= -1-2 ; -x = -3 ; x=3. Hope this helps.
The value of x = (- 1 + 2√2)/4 satisfies the given equation.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expressions are equated by an equal sign.
The equation given is
(4x + 1)² - 8 = 0
x = (- 1 + 2√2)/4
To check whether it satisfies the equation
( 4 * ( (- 1 + 2√2)/4) +1)² -8 = 0
(-1 + 2√2 +1)² - 8 = 0
(2√2)² -8 = 0
8-8 = 0
As LHS = RHS ,
hence the value of x = (- 1 + 2√2)/4 satisfies the given equation.
