<em><u>Yo</u></em><em>ur answer would be rounded about </em><u><em>140</em></u> because first rectangle =108divided by 9 = 12 which was the the perimeter of the rectangle plus the 90 degree right triangle which was about 36 so there.
Step-by-step explanation:
Communicative property states that, in addition, integers added in any order will still give the same answer.
So in this question,
rather than first adding 8 + (-5), we add 8 + (-8)
We know that a number + its additive Inverse (opposite sign) is equal to zero
And we know any number added to zero is equal to the number.
So we can quickly find out that the sum is -5
R(–3, 1), S(4, 5)
calculate vector:
v=(4-(-3),5-1)=(7,4)
distance=length of vector=√(7²+4²)=√(49+16)=√(65)≈8.06226
rounded to the nearest tenth: 8.1
Answer:
sorry for the late...its done have a look
