X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
Answer:
x= 141.8179
Step-by-step explanation:
side a is 38, side b is 141.8179, side c is 146.8207
angle a is 15 angle b is 90 ancle c is 75
Answer:
They will sound together at 2pm
Step-by-step explanation:
Now, the first thing we need to calculate is , in how many minutes will the two gongs strike together.
To be able to do this, we need to calculate the least common multiple of the two numbers 24 and 40
The lowest common multiple between both is 120
This means that the two gongs will sound together at exactly 120 minutes
Now since 1 hour is 60 minutes, this means that 120 minutes will be = 120/60 = 2 hours
Since they both sounded together at 12 noon and the next time they will be sounding is next two hours, their sounding time will thus be 12 noon + 2 hours = 2 pm
Some schools do this differently, but since I don’t have any of the answer choices I’ll show you how to
Factor: -6|x+5|-2
Factor out the two
2(-3|x+5|-1)
And if you are looking for a graph here:
The slope cannot be found when only one co-ordinate is given.
One may assume the line is vertical or horizontal
This answer is ambiguous
