Step-by-step explanation:
83+30=113
The answer to this question is answer B
<u><em>Answer:</em></u>
-9
<u><em>Explanation:</em></u>
<u>From the first three </u><span><u>triominoes, we can note that:</u>
number on center = -first base - second base + vertex
<u>This is verified as follows:</u>
<u>For the first one:</u>
The two bases are 7 and 9 and the vertex is 1
- first base - second base + vertex = -7 -9 + 1 = -16 + 1 = -15
<u>For the second one:</u>
The two bases are 0 and 9 and the vertex is 8
- first base - second base + vertex = -0 -9 + 8 = -9 + 8 = -1
<u>For the third one:</u>
The two bases are 6 and 4 and the vertex is 2
- first base - second base + vertex = -6 - 4 + 2 = -10 + 2 = -8
<u>Applying the same procedure on the last one:</u>
The two bases are 7 and 2 and the vertex is 0
-first base - second base + vertex = -7 - 2 + 0 = -9 + 0 = -9
Hope this helps :)</span>
Answer:
Step-by-step explanation:
Given that,
(-10x - 7) - (3x - 10)
Note:
-×-=+
+×+=+
+×-=-
-×+=-
Then,
(-10x - 7) - (3x - 10)
Open bracket
-10x-7-3x+10
Collect like terms
-10x-3x-7+10
-13x+3
Then, the answer is -13x+3.
Answer: It should be the third one
