Answer:
60√3
Step-by-step explanation:
All we are doing here is multiplying:
12√75
60√3
Alternatively, we could plug this into a calc and figure out our answer.
Point Q is the midpoint of GH
so GQ = QH
Given GQ=2x+3, and GH=5x−5 .
2x + 3 = 5x − 5
3x = 8
x = 8/3
GQ = 2(8/3) +3
GQ = 16/3 + 3
GQ = 16/3 + 9/3
GQ = 25/3
GQ = 8 1/3
Answer:
C
Step-by-step explanation:
It’s convenient that there are only two <em>x</em> values you need to check, -2 and 2. Just insert it to see what <em>y</em> is appropriate.
x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)
x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)
So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.
A isn’t in the solution set either with -5 < 4.
C is in the solution set with 5 > 4.
So for this problem we are looking for a sum (total). So first we are going to round 25.65 to 25.7 and round 14.23 to 14.2
Now we are going to add 25.7 and 14.2 to get a total of 39.9
