Answer:
The geometric mean of 6 and 30 is 13.416407864999
Answer:
The first answer is -2x^2-12x-19
The second answer is 2x^2+12x+17
Step-by-step explanation:
You can calculate the vertex of each one by using the formula -b/2a =x and then plugging that in for x to find y but that's a lot of work so I just plugged them into desmos
First, solve inside the absolute value box
4-16 = -12
Then, find the absolute value of -12
abs(-12) = 12
12 is your final answer.
Answer:
x = - 26
Step-by-step explanation:
Let the number be x.
According to the question,

Cross multiplying 4 & 3 gives :-

And solving this eqn. gives :-

Verification :-
(putting the value of x = -26 )

Reducing
by 7 gives
.
1 1/3 - 2/3 =
4/3 - 2/3 =
2/3 <==
