Answer:
5x+6
Step-by-step explanation:
(1/3*9x)+(1/3*16)+(1/3*2)+2x=
3x+16/3+2/3+2x=
5x+18/3=
5x+6
Because the medians are the same for both.
Answer:
72 degrees.
Step-by-step explanation:
If the angle is x degrees its complement is 90-x degrees and it's supplement is 180-x degrees.
4(90-x) = 2/3(180 - x)
360 - 4x = 120 - 2/3 x
360 - 120 = -2/3 x + 4x
240 = -2/3 + 12/3 x
240 = 10/3 x
x = 240 * 3/10
x = 72 degrees.
Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
Answer:
<h2>24</h2>
Step-by-step explanation:
Given the following logarithmic expressions 
, we are to find the value of 
Substituting x = a³, y = a⁷ and z = a⁻² into the log function we will have;
Hence, the value of the logarithm expression is 24
