Answer:
2 long x tiles and 3 long x tiles are like terms.
Step-by-step explanation:
You can do this by converting this into a ratio or a fraction
Ratio:
1 lb for 4 guinea pigs
1:4
If he was 8 lbs for x guinea pigsit would be
1:4
8:x
Multiply the first ration until the one is equal to 8, then whatever the four turns into is x
Fraction: (easier way)
1/4 (1lb for 4 guinea pigs)
8/x (8lb for x guinea pigs)
1/4 = 8/x
Multiply one until it is equal to 8
Correspond that to the 4
1*8 = 8
4*8 = 32
32 guinea pigs
The derivate is. f'(x)=2x+1 .then f'(-1)=-2+1=-1
Answer:
son weight = 72
