Answer:
D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Step-by-step explanation:
Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.
or, for any numbers A, B and C
A + ( B +C) = (A +B) + C
Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Answer:
False
Step-by-step explanation:
11 times 11 is 121
5 times 5 is 25
13 times 13 is 169
121+25 doesnt equal 169
this means it is not a right angled triangle as it does not follow pythag
Answer:
See below
Step-by-step explanation:
For a parallelogram m < A = m < C so:-
75 + 5x = 87 + 3x
2x = 12
x = 6
and m< A = 75 + 30 = 105
and m < C = 87 + 18 = 105
Now if the other 2 angles are = 75 degrees( that is the same side angles add up to 180 degrees) we have proved that it is a parallelogram.
m < B = m < D
111 - 6x = 39 + 6x
-12x = -72
x = 6
m < B = 111 - 36 = 75 and m < D = 39 + 36 = 75
So this has been proved.
Rounding the answer is 100.
