Step-by-step explanation:
∑k=150(3k+2)
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925
Hi!
<h3>To find the slope, use this formula</h3>

<h3>Put in the values</h3>

<h2>The slope is 1 </h2>
Hope this helps! :)

Step-by-step explanation:
(a-b)^2=a^2-2ab+b^2
X^2-2(X)(5)+5^2
Ans C
X^2-10X+25
Step-by-step explanation:
234751
100% sure
Goood luck.
.15x = 75
Divide both sides by .15 you get 500 minutes
