Answer:

Explanation:
The equation is asking for multiplication (13 * v), and the opposite of multiplication is division. So if we divide 65 by 13, we find 5.
13 * 5 = 65
Answer: –145 is the 25th term in this series where each term is 7 less than the preceding term.
Step-by-step explanation: Find the difference between the numbers given.
They are decreasing by 7.
The requested term is 25. Subtract -1 . = 24 (n-1)
Multiply 24 × -7 = -168
Add that to to first term
23 + (-168) = the 25th term
–145 is the 25th term in this series where each term is 7 less than the preceding term.
They are length and width. the only thing is that they do not have volume
Step-by-step explanation:
i) x (x+2)(3x)
ii) 3x^3+6x^2
iii) (x^2+2x) +(3x^2+6x) +(3x^2)
iv)7x^2+8x
