Answer:
y= (x+4)(x+4) is the answer
Step-by-step explanation:
Identity used= (a+b)²= a²+2ab+b²
To find the inverse of a function, we swap x and y then solve for y
So with this, we take y = 3x + 4 and make it x = 3y + 4. Now we solve for y
x = 3y + 4
Subtract 4 from both sides
x - 4 = 3y
Divide both sides by 3
Since both sides have a -2 in then you can pull it out making the equation -2(3*4) which equals -2(12) so A is correct
<u>Given</u>:
Given that the side of the regular polygon is 16 feet.
We need to determine the area of the polygon.
<u>Area of the polygon:</u>
The area of the polygon can be determined using the formula,

where n is the number of sides,
s is the side length.
Substituting n = 3 and s = 16, we get;

Simplifying, we get;


Dividing, we get;

Rounding off to the nearest tenth, we have;

Thus, the area of the regular polygon is 110.9 square units.
Answer:
D) The value cannot be determined from the information given
Step-by-step explanation:
If 3x−y=12, what is the value of 8x/2y ?
We can progress till:
- 3x-y=12
- y= 3x-12
- 8x/2y= 4x/y= 4x/(3x-12),
we need the value of x to determine the result.
So the answer is the last choice
