Answer:
4 sqrt(2)
Step-by-step explanation:
radical 50 - radical 2
I rewrite in terms of sqrt (means the same thing)
sqrt(50) - sqrt(2)
sqrt(25*2) - sqrt(2)
We know that sqrt (ab) = sqrt(a) sqrt(b)
sqrt(25)sqrt(2) - sqrt(2)
5sqrt(2) - sqrt(2)
Factor out the sqrt(2)
sqrt(2) (5-1)
4 sqrt(2)
Answer:
Negative
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
The "Absolute value" of both is 4.75
10 × -2 is -20
-20 -8 = -28
Answer:
33 and -39
Step-by-step explanation:
Angle on a straight line = 180
|5x + 15| = 180 and |5x + 15| = -180
5x + 15 = 180
Subtract 15 from both sides;
5x = 165
Divide both sides by 5;
x = 33
5x + 15 = -180
Subtract 15 from both sides;
5x = -195
Divide both sides by 5;
x = -39
