A*b=18 ____[1]
a+b=19____[2]
[2] a=19-b ___[3]
put [3] in [1]
(19-b)*b = 18
19b-b^2 = 18
b^2-19b+18 = 0
(b-18)(b-1) = 0
so b=18 or b=1
if b=18 then a=19-18=1
if b=1 then a=19-1=18
SO two factors are 1 and 18

Answer:
volume goes to 2.0 L
Step-by-step explanation:
At constant temperature, volume and pressure are inversely related. Increasing the pressure by a factor of 125/50 = 2.5 will cause the volume to be reduced by that factor.
volume = 5.0L / 2.5
volume = 2.0 L

Answer:
2
Step-by-step explanation:
4.0 has 2 significant digits.
The zeros after a non zero number are significant.
Any non zero number is significant.
0.004 has 1 significant digit.
4000 has 4 significant digits.
In your case 4.0 × 10^3 there is an exception because it is in scientific notation. So there are 2 significant digits.
hope this makes sense.

Answer:
Pythagorean Theorom: a^2+b^2=c^2
Take the largest number of each as C (hypotenuse)
<u>3,4</u><u>,</u><u>5</u>
(3)^2+(4)^2= (5)^2
25=25
Therefore it is a Pythagorean Triple.
<u>8,15,17</u>
(8)^2+(15)^2=(17)^2
289=289
Therefore it is a Pythagorean Triple.
