Answer:
3. Reflexive property of congruence
(since the statement states that a segment is congruent to itself)
4. SSS
(since 3 sides of one triangle are congruent to three sides of the other triangle)
Answer:
Since f(x) is a first order equation, it has only one zero
f(x) = -20*x +23*x -6
This means that
f(x) = (-20 + 23)*x -6
f(x) = (3)*x -6
If we mame the previous equation equal to zero ----->
(3)*x -6 = 0
x = 2
which means, the factorization is equal to
(x-2) = 0
f(x) = 3*(x-2)
Plug in 5 and 10 to the equation.
For the first one would be d(5) = 0.8(5)^2
Multiply the equation d(5) = 4^2
Then you just multiply the exponent the would be d(5) = 10
The second one, you just do the same thing and the answer would be d(10) = 64
