Answer:
√1924=43.86
Step-by-step explanation:
√(x2-x1)^2+(y2-y1)^2=√1924=43.86
2.52 x 3.4
= (2.50 + 0.02)(3.00 + 0.40)
= 2.50 x 3.00 + 2.50 x 0.40 + 0.02 x 3.00 + 0.02 x 0.40
= 7.500 + 1.000 + 0.060 + 0.008
= 8.500 + 0.060 + 0.008
= 8.560 + 0.008
= 8.568
Step-by-step explanation:
factor out x because that variable is common in all 3 terms
x (x2 - x - 12)
now you can factor
x (x-4) (x+3)
when you use FOIL you will see you arrive at the original answer.
so yes it is a factor

Answer:
Angela is 13 years old and Angela's aunt is 41 years old.
Step-by-step explanation:
With the information provided you know that Angela's aunt is two more than three times her age, which could be expressed as:
x=3y+2, where:
x is Angela's aunt age
y is Angela's age
Also, you know that the total of their ages is 54, which is:
x+y=54
Now, you can replace x=3y+2 in x+y=54 and solve for y:
3y+2+y=54
4y=54-2
4y=52
y=52/4
y=13
Finally, you can replace the value of y in x=3y+2 to find x:
x=3(13)+2
x=39+2
x=41
According to this, the answer is that Angela is 13 years old and Angela's aunt is 41 years old.
