Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
SA = 2<span>(<span><span><span>wl</span>+<span>hl</span></span>+<span>hw</span></span><span>)
SA = </span></span>2<span>(<span><span><span>(3)(10)</span>+<span>(8)(10)</span></span>+<span>(8)(3)</span></span><span>)
Multiply:
SA = 2(30 + 80 + 24)
Add:
SA = 2(134)
Multiply:
SA = 268</span></span>
Answer: The slope of the line is 
.
Explanation:
From the given graph it is noticed that the line passing through many points.
The coordinates of three given points are (-6,6), (0,4) and (6,2).
If a line passing through two points 
and 
, the slope of the lie is defined by,
The line passing through two points (0,4) and (6,2). So the slope of the line is,
Therefore, the slope of the line is .
It's decreasing to the left and increasing to the right
