Answer:
Step-by-step explanation:
1). Geometric mean of a and b = 
Therefore, geometric mean of 2 and 50 = 
= 10
2). By geometric mean theorem,
e² = 6 × 24
e = √144
e = 12
Similarly, 
d² = 6 × 30
d = √180
d = 6√5
And 
c² = 30 × 24
c = √720
c = 12√5
Answer:
15 equation: 195=105+6x
Step-by-step explanation:
he starts out with 105 and the rate of change is 6x so to get the answer u wanna make and equation (195=105+6x) then you would subtract the 105
195=105+6x
-105 -105
---------------------
90=0 +6x
then u would divide by 6
90/6=6x/6
x=15
D. -2p + q - 5 - you have to multiply, then distribute parentheses and apply plus or minus rules.
Answer:
14
Step-by-step explanation:
we are solving 15 + |-3| - 4
anything inside | | means it's absolute value.
absolute value means that even if it is a negative number inside, it will change to positive. if it is a positive number inside, it will stay the same.
so |-3| is 3.
15 + 3 - 4
18 - 4 = 14.
we got the answer
