Answer:
A = 6x² + 97x + 391
Step-by-step explanation:
Given that,
The length of the shop, l = (3x+23)
The width of the shop, b = (2x+17)
The expression for the area of the shop is given by :
A = lb
Put all the values,
A = (3x+23) × (2x+17)
= 6x² +51x+46x +391
= 6x² + 97x + 391
Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.
It would be the last option.
2:14, 1:7, 3:21, and 18:126
They are all multiplying by 7.
2*7= 14
1*7= 7
3*7= 21
18*7= 126
Hope this helps! :)
3 is correct , base is never equal to 1 cause all of solves of logarithm will be 0
