Step-by-step explanation:
perimeter=(L+W)2
L=x^2+2x-3
W=2x^2+3x+5
(x^2+2x-3+2x^2+3x+5)2
(x^2+2x^2+2x+3x-3+5)2
(3x^2+5x+2)2
p=(6x^2+10x+4)units
Answer:
28
Step-by-step explanation:
10 - (-18)
=> 10 + 18
=> 28

Answer:
T(h) = 20 - 3h
Step-by-step explanation:
We are told that for every km you go up, the temp goes down 3°.
Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h
If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°
If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°
If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°
Large would be 1495
Medium would be 997
Small would be 498
Look a the work I did, it has an equation in it. The equation I got is 3x+2x+x=2940
