Answer:
1/2d+c^2-b = 21
Step-by-st ep explanation:
= 1/2(10) + 5^2 -9
= 5 + 25 - 9
= 30 - 9
= 21
We should first find where the graph doesn't exist, which would be where the denominator is equal to 0 or the formula under the radical is negative. So we can write the equation x-3≤0 to find where the graph can't exist
x-3≤0
x≤3
So this means that no x values less than or equal to 3 can exist on this graph. So the only choice that isn't less than or equal to 3 is choice 2 (7)
Hope this helps

Answer:
There is a circle with a diameter[d] of 2.
Step-by-step explanation:
the Radius=diameter /2=2/2=1 units
now
circumference=2πr=2×π×1=6.29=6 units
area=πr²=3.14 unit²
1. Given (12+3)x, we can sum the numbers in the parenthesis to get 15x
2. Given 12x+3x, we can factor x to get (12+3)x and get the same as 1.
3. Given (12+3x)x, we have to distribute the x and we have 
4. This expression is already simplified.
