The width is 3m because 3*7 is 21m^2. Also they said the length is 4 more than the width (3+4=7)
2b=12-18
2b=-6
b=-3
That is the answer
Answer:
f(-3) = 2
f(-1) = 2
f(8) = 1
Step-by-step explanation:
Yep! For any function f(x), you find the y value corresponding the x value. For example, in this question, it asks us to find f(-3). Therefore, you go to the line, x = -3, and see where it intersect the function (the y value). Your answer would be the y value.
The value corresponding to f(-3) seems to be 2.
The value corresponding to f(-1) seems to be -2.
The value corresponding to f(8) seems to be 1.
Answer:
The answer is d. 22.5.
Step-by-step explanation:
(2x+5) degrees = 50 degrees
2x = 50 - 5
2x = 45
x = 45/2
x = 22.5
