Answer:
25x^2 - 16.
Step-by-step explanation:
(5x+4)(5x-4)
F = 5X*5X = 25X^2
O = 5x * - 4 = -20x
I = 4 + 5x = 20x
L = +4 * -4 = -16
So its
25x^2 - 20x + 20x - 16
= 25x^2 - 16.
Answer:
AB is A
BC is B
AC is D
Step-by-step explanation:
To find the length of each side, use the formula for the distance between coordinate pairs.
We can find the distance using the distance formula:
<u>AB</u>
We then substitute (-3,6) as
and (2,1) as
.
<u>BC</u>
We then substitute (2,1) as
and (9,5) as
.
<u>AC</u>
We then substitute (-3,6) as
and (9,5) as
.
The triangles are equal because they follow AAS congruency fact.
