Answer:
4
Step-by-step explanation:
Rate of change = Slope (if Sidelength = x, and perimeter= y)
(1,4) and (2,8) are point (if it was a line)
Use the slope formula...
(8-4)/(2-1)=
4/1=
4
Answer:
A = 9r^2
Step-by-step explanation:
r=√A/3
multiply both sides by 3
3r = √A
Square both sides
3^2 * r^2 = A
9r^2 = A
Well, Mathematics can enhance your analytical and problem-solving skills, expands the mind to handle difficult or unfamiliar tasks, and also promotes cautious and careful thinking. Once you know what the words mean you'll be able to write different variable expressions. Like I said it enhances our minds and helps think and solve probelms.
The shortest side is 3 m and the other side is 4 m. If you put all these numbers in the Pythagorean Theorem it checks out. (3^2+4^2=5^2)
