Answer: 4,5
Step-by-step explanation:
No, it has more than one. A rectangle is symmetric with respect to its diagonals, and the lines connecting the midpoints of two opposite sides.
<u>Answer</u>
D.25x2 – 36
<u>Explanation</u>
A. x² – 16x + 64
product = 64
sum = -16
factors: -8 and -8
x² – 16x + 64 = x² - 8x - 8x + 64
= x(x - 8) - 8(x - 8)
= (x - 8)(x-8) = (x-8)² ⇒ Not a difference of squares
B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares
C.9x² – x – 36
product = - 324
sum = -1
Factors: none
9x² – x – 36 ⇒ Has no perfect roots.
D.25x² – 36
25x² – 36 = (5x)² - 6² ⇒ This is the difference of squares.
Answer:
<em>Draw a circle of some radius. Divide the central angle (360 deg) into 6 equal parts of 60 each by a protractor. Join the points where the lines dividing the angle meets the circumference of the circle.</em>
Step-by-step explanation:
Six sides have the same length and the angles formed by six intersections of lines are correct. If either side has a length different from any other side, or if any of the angles differs from any other, it is not correct.
