x

2
x
=
−
5
Explanation:
x
2
+
7
x
+
10
=
0
We could right the equation in another form using brackets.
(
x
+
2
)
(
x
+
5
)
=
0
In order to get two numbers to multiply and give 0, at least one number has to be 0.
a stands for the first bracket and b for the second.
a x b = 0
a=0 or b=0 to make this equation valid.
Therefore x= -2 or x= -5 because -2+2=0 and -5+5=0 according to both brackets.
Answer:
you have a 7/12 chance
Step-by-step explanation:
The sample space has 12 elements:
T1, T2, T3, T4, T5, T6
H1, H2, H3, H4, H5, H6
(From a combinatorics perspective, there are 2 options for the coin and 6 for the die for a total of 2 * 6 = 12.)
There are 6 heads results and one tales result that has a 4 for a total of 7 possibilities that meet your criteria. That makes the probability 7 / 12.

Answer:
The stack will be 4.54 feet tall
Step-by-step explanation:
Firstly, we want to write the decimal expression for 2 3/11
That will be 2 + 0.2727
To 2 decimal place, that will be 2.27
Staking the two boxes means we are placing one on the other
So the height of the stack will be 2.27 + 2.27 = 4.54 feet
2×9=18+1=19 that what i think the answer is .
Would it be 270? if you take 90 3 times. due to that there are 3 different durations.
