Answer:
-7-√15
Step-by-step explanation:
First move the constant to the right hand side and change it's sign
x^2+14x=-34
Then add (14/2)^2 or 7^2 to both sides
x^2+14x+49=-34+49
Then factor the expression
(x+7)^2=-34+49
Then solve (x+7)^2=15
You should get:
x=-√15-7
or
x=√15-7
Answer:
3 1/4
Step-by-step explanation:
3/4 + (1/3 divided by 1/6) - (- 1/2)
first calculate between the brackets.
(1/3) / (1/6)
Division is the inverse of multiplying.
(1/3) * (6/1)
multiply both numerators and multiply both denominators
1*6 / 3*1 = 6/3 = 2
3/4 + (2) - (- 1/2)
make all denominators into 4
3/4 + (8/4) - (- 2/4)
- ( - = plus
3/4 + (8/4) + 2/4
3/4 + 8/4 + 2/4
add all numerators since the denominators are all the same.
( 3 + 8 + 2 ) / 4
13/4
3 1/4
3.25
