Combine like terms

10a-10a+3a = 3a
2b+2b + 4b
ab2-10ab+4ab-7ab2 = - 18ab

answer: 3a + 4b + 18ab

10a^2b + ab^2 - 10ab + 3a^2b + 4ab - 7ab^2

Combine like terms:
= 13a^2b - 6ab  - 6ab^2

Take out common factor ab:
= ab(13a - 6  - 6b)

bulgar [2K]
<h3>Answer:</h3>

\huge{\boxed{72}}

<h3>Explanation:</h3>

First, find the total number of apples.  6*1200=7200

Now, multiply this by the probability of picking a rotten apple, which is \frac{1}{100}.  This is also the same as dividing by 100, or moving the decimal point two places to the left.  7200*\frac{1}{100}=72

This means that based on the probability given, 72 rotten apples will be picked.

Lelu [443]

Answer: Phillip is correct. The triangles are <u>not </u>congruent.

How do we know this? Because triangle ABC has the 15 inch side between the two angles 50 and 60 degrees. The other triangle must have the same set up (just with different letters XYZ). This isn't the case. The 15 inch side for triangle XYZ is between the 50 and 70 degree angle.

This mismatch means we cannot use the "S" in the ASA or AAS simply because we don't have a proper corresponding pair of sides. If we knew AB, BC, XZ or YZ, then we might be able to use ASA or AAS.

At this point, there isn't enough information. So that means John and Mary are incorrect, leaving Phillip to be correct by default.

Note: Phillip may be wrong and the triangles could be congruent, but again, we don't have enough info. If there was an answer choice simply saying "there isn't enough info to say either if the triangles are congruent or not", then this would be the best answer. Unfortunately, it looks like this answer is missing. So what I bolded above is the next best thing.
