Answer:
x = 4
31x + 6 = 130
12x + 2 = 50
Step-by-step explanation:
two angles side by side are equal to 180.
(31x + 6) + (12x + 2) = 180
43x + 8 = 180
43x = 172
x = 4
31x + 6 = 124 + 4 = 130
12x + 2 = 48 + 2 = 50
Answer:
95 square meters
Step-by-step explanation:
I am answering this question assuming 19 is the base because it is the longest side on the triangle. (there is no picture provided)
The formula for area of triangle is base * height * 1/2
So 19 * 10 *1/2 is 95.
Answer:



Step-by-step explanation:
The given function is

We need to find first partial derivatives of the function.
Differentiate partially w.r.t. x and y, z are constants.


Differentiate partially w.r.t. y and x, z are constants.


Differentiate partially w.r.t. z and x, y are constants.



Therefore, the first partial derivatives of the function are
.
C=2x Pi x R so 2x3.14x17.5 = 109.9
Answer:
-2x + 4y - 2z
Step-by-step explanation:
as you can see, the graph indicates which axis belongs to x, y, and z and also gives information on the positive and negative directions of each axis.
to get the answer, all you have to do is find each coordinate,
x is at -2, y is at +4, and z is at -2.
