<span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>−5</span>−<span>(<span><span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>−4</span>)</span></span>
So first
Distribute the Negative Sign:
<span>=<span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>−5</span>+<span><span>−1</span><span>(<span><span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>−4</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>−1</span><span>(<span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>)</span></span></span>+<span><span>(<span>−1</span>)</span><span>(<span>−4</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>8a</span>b</span></span>+4</span></span><span>=<span><span><span><span><span><span>−<span>ab</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>8a</span>b</span></span>+4
</span></span>
Then after all of that
Combine Like Terms:<span>=<span><span><span><span><span>−<span>ab</span></span>+<span>8a</span></span>+<span>−5</span></span>+<span><span>8a</span>b</span></span>+4
</span></span><span>=<span><span><span>(<span><span>−<span>ab</span></span>+<span><span>8a</span>b</span></span>)</span>+<span>(<span>8a</span>)</span></span>+<span>(<span><span>−5</span>+4</span>)
So now your answer is </span></span></span><span>=<span><span><span><span>7a</span>b</span>+<span>8a</span></span>+<span>−<span>1</span></span></span></span>
Answer:
1-(n+6) (n+6)-1
Step-by-step
i just got it right on study island
Area = Length x Width
4 times it's width
4x8=32
Length = 32
Width = 8
32 x 8 = 256
Answer:
sorry I don't know
Step-by-step explanation:
Trapezoid, height 7, bases 5 and 6, so
area = (1/2) (6 + 5)(7) = 77/2 = 38.5
Answer: 38.5
As a check it's a 7×5 rectangle plus a 7×1 right triangle, so
A = 7×5 + 7×1/2 = 35 + 3.5 = 38.5, good
