Answer:
L=150 W=50
Step-by-step explanation:
150 is 3 times 50, 150+150+50+50 is 400
512.45
312+199.95=512.45
You would use the distributive property.
2(x+4) = 2x+8
2x+8x = 2x+8
10x = 2x+8
10x - 2x = 2x-2x+8
8x = 8
8x/8 = 8/8
x = 1
To find the answer, use , and then use the equation To find it's half life.
