Answer:
The 'n = 1' below sigma represents the <em>lower </em><em>bound</em><em>.</em> meaning the number from which you start adding.
'25' above sigma is the <em>upper </em><em>bound</em><em>.</em>
In general it means adding 42 from 1 to 25 times.
so 42(25).
Length = 12 (2x4)+4
width = 4
(2w+4) +(2w+4)+w+w = 32
6w +8=32
6w =24
w=4
l=12
4+4+12+12=32
Answer:
Step-by-step explanation:
5(d - 68) = 85
Use distributive property
5*d - 68*5 = 85
5d - 340 = 85
Add 340to both sides
5d = 85 + 340
5d = 425
Divide both side by 5
d = 425/5
d = 85
Answer:
0.32 and 8/25.
