A. Corresponding parts of congruent triangles are congruent.
Answer:
-63, 38
Step-by-step explanation:
1st number = x
2nd number = x+101
x+x+101=-25
2x=-126
x=-63
1st number = x = -63
2nd number = x+101 = 38
It's simple,
f(x)=x^2+2
is the formula that you start with
you are then given f(x). f(4x)
you then plug in 4x
4x=(4x)^2+2
you then solve for x
4x=16x+2
-16x. -16x
-12x=2
÷-12. ÷-12
x=0.16 is your answer
Answer:
C.41
Step-by-step explanation:
Thats the answer!!
The height of the tree is 60 meters.
Explanation:
Let the height of the tree be x. The tree casts a shadow of 
meters and the distance from the top of the tree to the end of the shadow is 
meters.
The sides of the triangle are attached in the image below:
Using pythagoras theorem,
Expanding, we get,
Solving the equation using the quadratic formula 
, we get,
Simplifying, we have,
Thus,
and 
where the value 
is not possible because substituting the value in results in negative solution. Which is not possible.
Hence, the value of x is 60.
Thus, The height of the tree is 60 meters.
