You must factor.

The factored form is equal to the assigned form.

Values a, b correspond to the factored 1, -1.
Value of x however remains unknown. But we can change that.
Given factored result,

We can set expression equal to 0 then find such x that when added with number a or b results with 0.

Hence x has 2 solutions.

Hope this helps.
Answer:
x = 30
Step-by-step explanation:
-2x + 10 +4x=70
-10 -10
-2x + 4x = 60
2x = 60
/2 /2
x = 30
Answer:
Step-by-step explanation:
Probability of an event occurring is the ratio of the number of time the event occur over the total sample space
Total sample space is 504 ways
Now, the event that you win the first prize and your mum wins the second price, can only occur in one way, their is no other way it can occur
Therefore,
Pr(you win first prize and your mom wins second prize) = 1 / 504
So, the correct answer is C.
Answer:
5 feet
Step-by-step explanation:
The scale factor = 1 inch: 1.25 feet
The length of the Hally = 4 inches
The length of the hallway in real life is calculated as:
1 inch = 1.25 feet
4 inches = x feet
Cross Multiply
x feet = 4 × 1.25 feet
x feet = 5 feet
Therefore, the length of the Hallway in real life is 5 feet
Do you know how to change the 1 hour to minutes
