<span>A square will always be a parallelogram due to the definition of a square.
A parallelogram is a quadrilateral with two pairs of parallel lines. Each two opposite sides are equal and none of the angles is right.
A square is a quadrilateral with 2 pairs of parallel sides, all right angles and all congruent sides.
Since it is part of the definition, it is impossible to have a square that is not a parallelogram.</span>
Answer:
The required expression is 
Step-by-step explanation:
Let the number be x
We are supposed to write the algebraic expression of given statement
Double the number = 2x
Quotient of five and two =
Now we are given that Double the sum of a double the number and quotient of five and two
So, Sum of a double the number and quotient of five and two =
So, Double the sum of a double the number and quotient of five and two =
Hence The required expression is
Answer:
40
Step-by-step explanation:
Quadratic function ( in standard form ):
y = a x² + b x + c
x = 0:
635 = 0 + 0 + c
c = 635
x = 1:
644 = a + b + 635
a + b = 9
x = 2:
719 = 4 a + 2 b + 635
4 a + 2 b = 84
and now we have a system:
a + b = 9 / * ( - 2 )
4 a + 2 b = 84
-------------------------
- 2 a + 2 b = - 18
+
4 a + 2 b = 84
-------------------------
2 a = 66
a = 33; b = - 24;
Function is:
f ( x ) = 33 x² - 24 x + 635
f ( 8 ) = 33 * 64 - 24 * 8 + 635 = 2,112 - 192 + 635 = 2,555
Answer: The number of waterfowl on week 8 would be 2,555.
Four point two-hundred ninety three
