2(14)+2w=48  divide both sides by 2

14+w=24 subtract 14 from both sides

w=10

So the width is 10 meters.

In this problem we are trying to find the value of "W".

The values given are

·Y=48
·w=unknown
·2(14)=28

So we know that 28+2w=48, in order to solve for W, we would need to first subtract 28 from both sides

·2w=20

And now we would find the greatest common factor and devide both sides by that value, in this case its 2.

·2w/2=20/2
·20/2=10
·w=10

In conclusion W=10

alexandr1967 [171]

A sector is a <u>part</u> of a <u>circle</u> that is formed by two<em> radii,</em> and an <em>arc</em>. So that the length of the <em>safety railing</em> required is 31.4 feet.

A sector is a <em>part </em>of a <u>circle</u> that is formed by two <u>radii</u>, and an <u>arc</u>, thus forming a <em>central</em> angle.

Thus the required <em>length</em> of safety railing can be considered as the <u>arc</u> of the<em> sector. </em>

So that;

<u>length</u> of an <u>arc</u> = (θ / 360^{o}) * 2\pir

where θ is the <u>measure</u> of the <em>central angle</em> of the sector, and r is the <u>radius</u> of the sector.

From the given question, θ = 45°, and r = 40 feet.

So that,

<u>length</u> of the<em> safety railing </em>= (45° / 360^{o}) * 2 * 3.14 * 40

                                 = 0.125 * 2* 3.14* 40

<u>length</u> of <em>safety railing</em> = 31.4

Therefore, the <u>length</u> of the <em>safety railing</em> required is 31.4 feet.

34(4a + 12) = 21 a = <br> please find my answer
noname [10]

Answer: a = 2,84

Step-by-step explanation:

34(4a + 12) = 21 a =

136a + 408 = 21

136a = -408 + 21

136a = - 387

a =   <u>- 387 </u>

         136

a = - 2,84
