Step-by-step explanation:
The diagonals of a parallelogram bisect each other , then
CO = OA = b
DO = OB = a
(a)
CA = CO + OA = b + b = 2b
(b)
DC = DO + OC = a - b
(c)
CB = CO + OB = b + a = a + b
24=2(w+4)+2w=4w+8, subtract 8 from both sides 4w=16, w=4. L=w+4 so l is 8. The dimensions are 8 by 4.
Answer:
Step-by-step explanation:
Note that the expression is the difference of squares.
36 - 9m² = 6² - (3m)²
6² - (3m)² = (6 + 3m) (6 - 3m)
True.
Using the pythrngeon theorem, we can say that west (15m) = A, north (8m) = B, and the 17m will be C.
For the theorem, it only holds true if a^2+b^2=c^2
So, if a = 15 and b = 8 , 15^2 = 225 and 8^2 = 64 .. 225+64=289.
Therefore c^2 must equal 289. The square root of 289 = 17, or 17^2=289. so the statement is true.
