10x2 – 25x + 7
10x2 – 25x + 11
Answer:
A.) 8x2 – 25x + 7
Step-by-step explanation:
The expression A² – (B + C) in its simplest form is 8x² – 25x + 7
Data obtained from the question A = 3x – 4B = x + 7C = x² + 2A² – (B + C) =? How to express A² – (B + C) in its simplest formA² – (B + C)

9x² – 12x – 12x + 16 – (x + x² + 9)
9x² – 24x + 16 – x – x² – 9
9x² – x² – 24x – x + 16 – 9
8x² – 25x + 7

Answer:
(c) No, it is not a rectangle because the diagonals are not congruent
Step-by-step explanation:
The diagonals of a rectangle bisect each other and are the same length. The lengths of the diagonals of this figure are ...
AC = √((8-0)² +(6-2)²) = √(64+16) = 4√5
BD = √((5-3)² +(2-6)²) = √(4 +16) = 2√5
The diagonals are different lengths, so the parallelogram is not a rectangle. This is described correctly in choice C:
No, it is not a rectangle because the diagonals are not congruent.
_____
The lengths are found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
It's C, the diagonals are not congruent (they aren't equal) and with rectangles they always have to be.

#17. The height, H metres, of a certain species of Fir
tree can be estimated from the formula.
h= 35d , where d metres is the diameter at the
base. use the formula to determine the approximate
height of a fir tree with base diameter 3.2 m.
Answer:
The approximated height of the tree is of 112 meters.
Step-by-step explanation:
The height of a tree with a base diameter of d meters is approximated by the following formula:
[tex]h = 35d[/tex]
In this question:
Base diameter of 3.2m, so [tex]d = 3.2[/tex], and the height is in meters.
[tex]h = 35d = 35(3.2) = 112[/tex]
The approximated height of the tree is of 112 meters.
Answer:
The answer actually is 76m
