P = 2(L + W)
P = 68.4
L = 4W + 9.7
68.4 = 2(4W + 9.7 + W)
68.4 = 2(5W + 9.7)
68.4 = 10W + 19.4
68.4 - 19.4 = 10W
49 = 10W
49/10 = W
4.9 = W <==== the width is 4.9 cm
L = 4W + 9.7
L = 4(4.9) + 9.7
L = 19.6 + 9.7
L = 29.3 <=== the length is 29.3 cm
Answer:
4y^2-y+21
Step-by-step explanation:
(4y-5y)+(5y^2-y^2)+(-6+27)
-y+4y^2+21
put it in standard form
4y^2-y+21
Where are the functions? I can't help unless I can see the problem.
The answer for your question is (x,y)=(4,9)
This is a form of the Pythagorean Theorem. We just need to know how far we went in the x direction and how far in the y direction then use
a^2 + b^2 = c^2 to find the value.
distance in the x direction (-4 to -4) that's easy it didn't move. so that is zero and thus would make the distance all in the y direction.
To move from 8 to -8 we take (8 - (-8)) = 8 + 8 = 16 which is your answer
