J =Jorge
if the sum is no less than 25 then the best result to the question is Jorge is 8, while his brother is 9, but to put that in an inequality it'll be 2x+2j - 2 is greater than or equal to (couldnt use intended symbol)...25
Answer:
Graph the line using the slope and y-intercept, or two points.
Slope: -1/3
Y-Intercept: (0,1)
perimeter = 2L+2W
L=2+w
40 = 2L+2W
40= 2(2+w)+2W
40=4+2w+2w
36=4w
w=9
L=9+2=11
2(9) = 18, 2(11) = 22, 22+18 = 40
L=11
W=9
Area = L x w
area = 11x9= 99 square yards
A total of 35+21 = 56 tickets were sold. The probability of 5 men winning is the ratio
C(21, 5)/C(56, 5) = 20,349/3,819,816 ≈ 0.00533
_____
C(n, k) is the number of ways k items can be chosen from n items. Its value is
= n!/(k!*(n-k)!)

Answer:</h2>
(a) Describe a property of squares that is also a property of rhombi =
- The sides are the same length. The opposite angles are equal.
- Each of the diagonals is the same length and intersects at right angles to each other.
- The point of intersection of the diagonals divides the diagonal into two equal parts.
- Has two axes of symmetry.
- Can be framed with exactly four ways.
- Has a half-turn symmetry.
(b) Describe a property of squares that is not a property of rhombi =
- Has 4 axes of symmetry and rotational symmetry level 4
- Can occupy it in 8 ways
- All four sides are the same length (AB = SM = CD = AD)
- Parallel sides (AB // CD and BC // AD)
- Each angle is the same size as a square
- The diagonals are the same length (BD = AC)
- The diagonals intersect at right angles and bisect the length (AO = OC = BO = OD)
(c) Describe a property of squares that is not a property of rhombi =
- Opposite sides are parallel and the same length (AB = DC and AB // DC, AD = BC and AD // BC) The opposite angles are equal ( and).
- Two adjacent angles are 180o or are complementary.
- Sum of all angles = 360o Its diagonals divide the parallelogram into two equal parts.
(d) Describe a property of rectangles that is not a property of parallelograms =
- Has four sides that are the same length.
- Has four right angles.
- Has two diagonals that intersect at right angles to each other.
- Has quadruple symmetry rectangular.
