Hello!
Answer:
12(3+4+5+...+12+13)= 1,056
Step-by-step explanation:
After evaluating the expression it gave me : 1,056
Hope this helps!
1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5
2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.
3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.
C. multiplication (the 8 x 9 within the parenthesis)
It is 10 to 1 significant figures
