Answer:
4L = 4(3x + 8)
So,we can conclude that four times the side length is equal to the perimeter.
Step-by-step explanation:
Let the side length of the square be L.
We know that perimeter of a square is given as: P = sum of all 4 sides.
Thus, since all sides of a square are equal, then P = L + L + L + L = 4L
We are given that the perimeter is 12x + 32.
Since we have established the formula for perimeter as 4L
Thus;
4L = 12x + 32
So, if we factorize the right hand side, we have;
4L = 4(3x + 8)
Comparing both sides, we can see that L = 3x + 8
Thus,we can conclude that four times the side length is equal to the perimeter.
Answer:
The x-intercepts, or zeros, which are the values of x(or a in this problem) for which the function is 0, are x = a = -2 and x = a = -3.
Step-by-step explanation:
Suppose we have a function y = f(x). The zeros, which are the values of x for which y = 0, are also called the x-intercepts of the function.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
In this question:
I will write the function as a function of x, just exchanging a for x.
The x-intercepts, or zeros, which are the values of x(or a in this problem) for which the function is 0, are x = a = -2 and x = a = -3.
15 fish* (1 ft^3/ 0.3 fish)= 50 ft^3.
(Note that the unit cancels out so you get the answer)
The volume of the tank is 50 ft^3~
4/AC = AC/9
AC ^2 = 36
AC = 6
