All you have to do is replace every x with 2 and then solve:
<em>Make to sure to follow the Order of Operations!!</em>
-9x(2) + 11x - 7 =
(-9 × 2 × 2) + (11 × 2) - 7 =
-36 + 22 - 7 =
-14 - 7 =
-21
The answer is -21.
Hope that helps!
If the diameter is 2 and the radius is 1 then the volume is V = 2.0943951 m^3
The opposite angles of a cyclic quadrilateral add up to 180 degrees , so
2x + 3 + 4x + 3 = 180
6x = 180 - 6
6x = 174
x = 29
so m<C = 2(29) + 1 = 59 degrees
Answer:
0.65
Step-by-step explanation:
To get 13/20 to a decimal, the denominator needs to be multiplied by 5 to make it 100. If you multiply the denominator, you also have the multiply the numerator to make it equal. 13 x 5 is 65. The fraction is 65/100, which is 0.65 in decimal form.
Question:
Solution:
Let the following equation:
![\sqrt[]{12-x}=\text{ x}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B12-x%7D%3D%5Ctext%7B%20x%7D)
this is equivalent to:
![(\sqrt[]{12-x})^2=x^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B%5D%7B12-x%7D%29%5E2%3Dx%5E2)
this is equivalent to:
this is equivalent to:
thus, we can conclude that
x= 3.
