Answer:

subtracting 7 from 12

Step-by-step explanation:

That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives

5(3a-1)-2(3a-2)=3(a+2)+v
STatiana [176]

Answer:

<u>The answer is option C. 6a-7</u>

Step-by-step explanation:

Given that

5(3a-1)-2(3a-2)=3(a+2)+v

Solve for v

∴ v = 5(3a-1)-2(3a-2) - 3(a+2)

∴ v = 15a - 5 - 6a + 4 - 3a - 6

∴ v = 15a - 6a - 3a - 5 + 4 - 6

∴ v = 6a - 7

<u>So the answer is option C. 6a-7</u>

jolli1 [7]
I believe the answer is C - 60 inches. 60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.

Which is equivalent to (2^-3)^4 <br><br> 1/2^12<br><br> 2<br><br> -2^12<br><br> 1/2^7
sleet_krkn [62]

Answer:

The answer is First option

1/2^12 .

\frac{1}{2^{12} }

Step-by-step explanation:

Given:

(2^-3)^4

i.e

(2^{-3} )^{4}

To Find:

(2^{-3} )^{4}=?

Solution:

Law of Indices

(x^{a}) ^{b} =x^{a\times b}\\and\\x^{-1}=\frac{1}{x}

Using the above Property we get

∴ (2^{-3} )^{4}=2^{-3\times 4} \\\\ (2^{-3} )^{4}=2^{-12} \\\\(2^{-3} )^{4}= \frac{1}{2^{12} }

The answer is First option

1/2^12 .

(2^{-3} )^{4}=\frac{1}{2^{12} }
