Answer:
3x+27
Step-by-step explanation:
3(x+4+5)=
3x+12+15=
3x+27
295 she spent
y dollars she can spend on other expanses
then 295+x+y=500
implies x+y=205
Answer:
1. slope is 2
2. a is 5
3. b is 6
4. 0
Step-by-step explanation:
Hi,
Let assume a the west side,
b the length of the north wall (i suppose the answer is smaller then the barn.
Cost of the fence= a*6+a*12+b*12=3000 $.
So 3a+2b=500==>b=(500-3a)/2
Area =a*b=a(500-3a)/2= 250a-3/2a²
Derivate the area ==> 250-3a=0
==> a=250/3 and b=(500-3*250/3)/2=125
Width=125 (feet)
Length=250/3=83.333 (feet)
This would be a graph, a function is a straight line while a graph can be a scatter plot or something similar
