-4sqrt(x)-3 = 12 -> sqrt(x) - 3 = -3 -> sqrt(x) = 0
so x = 0, only solution, no extraneous solution
Answer:
1/4=0.25
Step-by-step explanation:
3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).
Here, we are given four inequalities, let us check them one by one-
A. h + 6 > -3h + 12
⇒ 4h > 6
or h > 3/2
Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.
B. 7 ≥ d/3
⇒ d ≤ 21
Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.
C. 3(x - 2) < 18
x - 2 < 6
x < 8
Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.
D. 2y ≤ 14
y ≤ 7
Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.
Thus, 3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.

the answer to ur question is going to be false it was right for me so i hope it is for u! good luck
Answer:
X^2 + 11x + 30
Step-by-step explanation:
x*x= x^2
x*6= 6x
x*5= 5x
6*5= 30
x^2 +6x+5x+30
Combine like terms
x^2 + 11x + 30
