Answer:
Yes your right
Step-by-step explanation:
For part A Amy's estimate is inaccurate because when adding fractions they must have the same denominators. Amy probably made the mistake of adding 1/4 and 1/3 without changing the denominators first which gave her 1/7. If she were to do it correctly then she would've ended up with 7/12 as her answer.
My work:
1/4=3/12
1/3=4/12
4/12+3/12=7/12
I hope this helps and if I gave any false information I apologize in advance.
Answer:
given,
base (b) = 2.25cm
height (h) = 1.5 cm
now,
area (a) = b×h
or, a=2.25cm×1.5cm
therefore the area of parallelogram is 3.375cm^2.

Answer:
it is eather d or b
Step-by-step explanation:
To multiply these, we use the FOIL method (first, outside, inside, last). Also, 1√2 is equivalent to √2. It's just like saying 1x is the same x.
Multiplying the first values will give you:
√2 * √6 = √12 = √4*3 = √2*2*3 = 2√3
Multiplying the outside values will give you:
√2 * -√10 = -√20 = -√4*5 = -√2*2*5 = -2√5
Multiplying the inside values will give you:
√6 * √6 = √36 = 6
Multiplying the last values will give you:
√6 * -√10 = -√60 = -√4*15 = -2√15
Now you can combine all of the resulting values:
2√3 - 2√5 - 2√15 + 6
I believe this is the answer you're looking for.
