Answer:
(6r+7)+(13+7r)=13r+20
(13-1/2r)-(1-r)=12-1/2r
(-8-r)+(2r-4)=-12+r
Last one is r-13/6
Step-by-step explanation:
<span>Parenthesis statements are evaluated first such that 7-2 Is 5.
From left to right, multiplication and division are evaluated: 5×4=20 6/3 =2
Finally addition and subtraction equating finally to: 32 + 20 - 2 = 50</span>
A. 314 sq cm
Explanation: pi•r^2
3.14 x 10^2
3.14 x 100 =314
Short answer: No afraid not.
Opposite sides of a parallelogram must be equal and parallel. The opposite sides of a kit are neither. To make sure you understand, measure the upper left side and the lower right side. The upper left is shorter than the lower right (even though these sides are opposite one another).
It you extend the upper left line upward and do the same thing to the lower right, you will get two lines that meet. No parallelogram will do that.
Zero is actually a whole number, rational number, and integer, but it is not a natural number
