Answer:
Step-by-step explanation:
27+36
=9×3+9×4
=9(3+4)
=9×7
=63
27+36=63
so 27+36=9(3+4)
Answer:
False.
Step-by-step explanation:
Two angles are complementary when added up, they give a result of 90°.
So, to this question to be true we have to do:
Angle 1 + Angle 2 = 90
But if we resolve 56° + 124° = 180, so this means that this question is false, as the addition of both angles doesn't have a result of 90°.
Answer
2/3+5/6= is 1.5
Step-by-step explanation:
first do 2/3=0.66666666666
and 5/6=0.83333333333
then do 0.66666666666+0.83333333333=1.5
Answer:
the requirements are missing:
- express the height of the rectangle in terms of w
- express the area of the rectangle in terms of w
1) the height of the rectangle is:
w + h + h + w = 500 + w
2w + 2h = 500 + w
2h = 500 + w - 2w = 500 - w
h = (500 - w) / 2 = 250 - 0.5w
2) the are of the rectangle is:
w x h = w x (250 - 0.5w) = 250w - 0.5w²
Answer:
The answer would be A.
Step-by-step explanation:
5 (-5)+ (2) = -23
-25 +2=-23
-23=-23!
