Answer: 1/4x + 1/2x = 12
x = 16
Step-by-step explanation: combine the 1/4x and 1/2x to 3/4x because they are like terms then divide 12 by 3/4 or 0.75 to get 16
B. but im not entirely sure
P=2l+2w
82=52+2w, (52 because 26*2=52)
30=2w
15=w
Answer: The width is 15ft
Answer:

Step-by-step explanation:
we know that
The exponential function is of the form

where
a is the initial value or y-intercept
b is the base or factor growth
r is the rate of change
In this problem we have
looking at the graph
Is a exponential growth function (as the value of x increases the value of y increases)
so

The y-intercept is the point (0,4)
so

substitute

From the graph take the point (1,8)
substitute in the exponential function and solve for b

therefore
The exponential function is equal to
