In order to get rid of the fractions, you need to multiply the equation by 12
C is the correct answer I believe
(2.5 x 10^-8)(9 x 10^-10) = (2.5 x 9) x (10^(-8 + (-10))) = 22.5 x
10^(-8 - 10) = 2.25 x 10^1 x 10^-18 = 2.25 x 10^(1 + (-18)) = 2.25 x
10^(1 - 18) = 2.25 x 10^-17
Answer:
<em>Subtract 225 from both sides. You have a
2 (or b
2
) =
400
. Square root on both sides. Therefore, a
2
(or b
2
), i.e. the other leg, is </em>
<em>20 cm.</em>
Answer:
Step-by-step explanation:
Since the angles both come off of the straight line, they are supplementary, and they add up to equal 180 degrees.
2x + 4x + 24 = 180 and
6x + 24 = 180 and
6x = 156 so
x = 26
