Step-by-step explanation:
+) Polygons ABCD has: A(-7;4); B(-5;7); C(-3;4); D(-5; 1)
+) Polygons A'B'C'D' has: A'(-9;0); B'(-7;3); C'(-5;0); D'(-7;-3)
The side lengths of ABCD:
The side lengths of A'B'C'D':
So that side lengths of ABCD equal to those of A'B'C'D'.
However, this is not enough to said that they are congruent polygons, as 2 polygons are congruent when they have all corresponding sides and interior angles are congruent.
ABCD and A'B'C'D' have all corresponding sides congruent.
=> <em>So that "all corresponding interior angles are congruent" must be true for them to be congruent polygons</em>
Answer:
The vertex form of a quadratic function is given by. f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.

Answer:
45,000 mL (Milliliters) = 45 L (Liters)
Explanation:
The word milliliters is made up of two words, "milli" and "liter"
"Milli" means a thousand, chiefly denoting a factor of one thousandth.
That means one milliliter is one thousandth of a liter
3/5= 60/100
still has 40/100 left
proportion- x over 75 = 60 over 100
cross multiply- 75*60=4500/100=45
75-45=30
Needs $30
30/7.5=4
Needs to work 4 hours
Hope this helped.
