20%= 0.2
0.2(360)=72
360+72=432
432-50=382

<span>You can let x = the length of the short side. Then the length of next largest side would be x+2 and the length of the largest side would be x+4. These sides add up to 195 mm. You can set up the equation to find x, the length of the short side.
Simplify and solve for x.
Subtract 6 from both sides of the equation.
Divide both sides by 3.
</span><span>
The length of the short side is 63 mm
The length of the middle side is x+2 = 63+2 = 65 mm
The length of the long side is x+4 = 63 + 4 = 67 mm
Check: 63+65+67 = 195 mm</span>

Answer:
D. None of these
Step-by-step explanation:
(5×10^8)(4×10^3)
=20 × 10^11
All the terms are being multiplied. There is no distributive property (FOIL) here. Rearrange the numbers in any order that helps you.
5 × 4 × 10^8 × 10^3
Add exponents to multiply the 10's.
and in proper scientific notation, one last change would give you
2.0 × 10^12
