Answer:
C.60
Step-by-step explanation:
4×12=48
18-12=6
6×2=12
48+12=60
Given:
Triangle:
height = 6ft
base = 4ft
Rectangle:
length = x
Width = 6 ft
Surface Area = 150ft²
Area of a Triangle = h*b / 2 = (6ft * 4ft) / 2 = 12ft²
Area of a rectangle = Surface Area - Area of a Triangle
A = 150 ft² - 12 ft² = 138 ft²
138 ft² = x * 6ft
138 ft² / 6 ft = x
23 ft = x.

Answer:
I think you wanna know exactly it's graph
See f(x)= 2 e^x +3
e^x is exponential function which is always positive and so lies above x axis
Multiply by 2 make it's incrementation in slope and now it will pass through (0,2)
Also adding 3 shifts graph 3 unit above y axis
So Now it will pass through (0, 2+3) that is B) (0,5)
Now At x approaches to minus infinity it will shift 3 unit up from 0 to 3 So it will pass through (-infinity,3)
Now see the pic
