Answer:
8.9k
Step-by-step explanation:
We just have to add together the length of the three sides to find the perimeter of the triangle.
(1.8k-5)+(3.5+6.1k)+(k+1.5) = 1.8k-5+3.5+6.1k+k+1.5
Combine like terms.
1.8k<em>-5+3.5</em>+6.1k+k<em>+1.5</em> = 8.9k <em>+ 0 </em>
= 8.9k
The correct answer is 4x-10
So she has 396460
she will withdarw 1700 per month, and withdraw is loss or minus or (-)
after x months, she has 359060 left so
total-withdrawn=remaining
withdrawwn=1700 times months so withdrawn=1700x
total-1700x=remaining
total=396460
reaining=359060
subsitute
isolate x then divide is the strategy
396460-1700x=359060
add 1700x to both sides
396460=359060+1700x
subtract 359060 from both sides
37400=1700x
divide both sides by 1700
22=x
she has been retired for 22 months
