Answer:

Step-by-step explanation:
Let the outside temperature be
degree.
So, when
degree, number of members, 
Now, for every degree rise in temperature, 10 members gets added.
So, when the temperature is
degrees, rise in temperature is
degrees.
Therefore,
For
degrees rise, number of members added = 
Hence, total number of members added as a function of temperature is given as the sum of members at
degrees and for
degrees rise. This gives,

Answer:
192 = (x^2 + 8x)/2
Step-by-step explanation:
we know the base is x and the height is x+8.
Area of the triangle is 1/2 bh.
we know h and x
if we take area to be 192, we can write the area to be;
1/2 x(x+8) =A

Answer:
21.75
Step-by-step explanation:
14.50 divide-by 2 = 7.25 so 14.50 + 7.25= 21.75
Answer:
4y+3x+17
Step-by-step explanation:
take the similar numbers and add them together.
1. -2y+6y = 4y
2. 5x-2x = 3x
3. 8+9 = 17
Put the numbers back together into the new and simplified equation: 4y + 3x + 17
Answer:
0
Step-by-step explanation:
-10 + 10
-10 and 10 are additive inverses, so when we add them, it is equal to zero
-10 + 10 = 0
