Which expression is equivalent to (see picture below)? 4[50(50+1)/2]^2+3(50)
4[50(50+1)/2]^2+3(50(51)/2)
4(50(50+1)(2x50+1)/6)+3(50)
4(50(50+1)(2x50+1)/6)+3(50(51)/2)
please hurry, it's timed

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

the answer is d

hope this
