Answer:
(a+b)(2x−ab+a−b)+x(a−b)+x²
Step-by-step explanation:
I can't make a good explanation, so here's a graph.
Also, this wouldn't be a proportional relationship because of exponents on the last term.
This is really a parabola.
We can assign variables to each side:
x = first side
y = second side
z = third side
We will assume the "one side" that is greater than the second side is the first side. Since it is "2 times the second side" we can write this as:
x = 2y
Since the third side is 5ft longer than the second side, we can write this as:
y + 5 = z
Perimeter of the triangle (49ft):
x + y + z = 49
We can substitute everything we know.
(2y) + y + (y + 5) = 49
4y + 5 = 49
4y = 44
y = 11
Now we can solve for the other sides with what we have for y.
x = 2(11)
x = 22
11 + 5 = z
16 = z
Add to check.
22 + 11 + 16
33 + 16
49
Therefore, the side lengths are [ 22, 11, and 16 ]
Best of Luck!
Answer:
7.4
Step-by-step explanation:
just divide it by 3.2
Answer:
The solution of the exponential equation is
x = 2.996
Step-by-step explanation:
To solve the exponential equation
First, we will isolate by dividing both sides of the equation by 4, so that we get
Now, we will take the ln of both sides of the equation to get
(NOTE: )
Then,
∴ x = 2.996 (to three decimal places)
Hence, the solution of the exponential equation is
x = 2.996
X is the bottom and y is the left side an it should be straight
