Answer:
I am pretty sure the anwser is 7
Answer:
Option (3)
Step-by-step explanation:
We have to divide polynomial given as (x³ - 21x² + 147x - 343) by (x - 7) by synthetic division.
7 | 1 -21 147 -343
<u> ↓ 7 -98 343 </u>
1 -14 49 0
Therefore, quotient is (x² - 14x + 49) and the remainder will be 0.
Option (3) will be the answer.
The length of the rectangle is x and the height is x-2
To find the area of a rectangle you multiply length times width
l(w) = 146
x(x-2) = 146
x^2 - 2x = 146
I = prt
420 = 7000 x .02 x t
420 = 140 x t
420/140 = 140 x t /140
t = 3 years
The correct answer is, obviously, 34/7.
