J less than or equal to 25(w) ? Idk if that’s right but that’s what I would do
X - 1/2 (if you meant the difference between)
Answer:19/2
Step-by-step explanation:
19/2=9.5
Other are not in its very simplest form
A. The hexagon as the series is adding a side each time. So you started with 3, 4, 5...
(1.2×10^2) + (3.04×10^5)
They must be to the same power to add
3.04 *10^5 to change to the 2nd power (5-2=3) move the decimal 3 places to the right = 3040. * 10^2
1.2 * 10^2 + 3040 *10^2=
add the numbers keep the exponents the same
3041.2 * 10^2
there can only be 1 number before the decimal in scientific notation so we need to move the decimal 3 places to the left, which adds 3 to the exponent
3.0412 * 10 ^ (2+3)
3.0412 * 10^5
