Answer:
Not a polygon
Step-by-step explanation:
[(3x+12)•(4x+4)]-(3x+8)-(4x)
[12x² + 12x + 48x + 48] - 3x - 8 - 4x
12x² + 60x + 48 - 7x - 8
12x² + 53x + 40
This is a degree 2 (quadratic) polynomial, not a polygon.
A polygon is an n-sided figure.
Example: A rectangle --> A four-sided polygon
Hello :) ok so to find AC you would have to use sin. It would be sin70= x/4. To find AC you would have to multiply 4 by sin70 which is 3.758 or to the nearest hundredth would be 3.76. I hope I helped, if you need a more in depth explanation lmk
I assume that the "d2" was a typo as a problem such as this with 2 variables would require a <em>system of equations</em>.
I also assume that the ? is a typo and will replace it with 0, however you can repeat my steps with whatever it actually it.
I assume that the correct form is 2 + 3a + 6 + a = 0
2 + 3a + 6 + a = 0
Combine like terms
8 + 3a + a = 0
8 + 4a = 0
move 8 to other side
4a = -8
a= -8/4
a = -2*
plug this value of a into the original equation
2 + 3(-2) + 6 + (-2) = 0
The statement is true!
<em>* This probably isn't your answer! Repeat my steps with whatever the value of "?" is.</em>
Answer:
(-3,8)
Step-by-step explanation:
When reflecting over the y-axis, you are switching from positive to negative x-values. Since 3 was already positive, we change the integer and in this case, to negative, so it becomes -3. Since the y value remains the same we don’t change the 8. So (-3,8)
I hope this helps!
Please give thanks or brainliest if this helps!
<h3>Calculate the area of the circle</h3>
To start solving this exercise, we obtain as data:
To find the area of the circle. We apply the following formula: A =π r², where
We substitute our data in the formula and solve:
Substituting values into the equation:
Taking the square root:
Multiplying
Therefore, the area of the circle is 300 ft².
