6 0

Answer:

(2x + 3 + 2√6)(2x + 3 - 2√6)

Step-by-step explanation:

<u>Factorization in steps</u>

  • 4x^2 + 12x- 15=
  • (2x)^2 + 2*2x*3 + 3^2 - 9 - 15 =
  • (2x + 3)^2 - 24 =
  • (2x + 3 + √24)(2x+3 - √24) =
  • (2x + 3 + 2√6)(2x + 3 - 2√6)

Answer:

The measure of angle B is 33 Degrees.

Step-by-step explanation:

The triangles are said to be similar. then their corresponding angles are equals.

\angle A  =  \angle M

\angle B  =  \angle O

\angle C  =  \angle P

Then from the given data,

\angle A  =  \angle M = 45^{\circ}

\angle C  =  \angle P = 102^{\circ}

Now according to the triangle sum property,

\angle A +  \angle B +\angle C = 180^{\circ}

45^{\circ} +  \angle B + 102^{\circ} = 180^{\circ}

147^{\circ} +  \angle B  = 180^{\circ}

\angle B  = 180^{\circ} - 147^{\circ}

\angle B  = 33^{\circ}

I really need help...can someone help me plz? A paper manufacturer is evaluating their packing procedures. Currently, they packa
UNO [17]

Answer:

To reduce the weight by 10 lbs you need to remove two reams of paper, leaving you with 10 reams. The only way to fit these into a cuboid would be 5 stacks of 2,  2 stacks of 5, 1 stack of 10 or 10 stacks of 1. You need to figure out the dimensions of paper arranged like that then work out the surface area. Obviously 1 x 10 or 10 x 1 will be stupid because the box would be awkward to carry, so the correct answer will be whichever of the other two gives you the least surface area (and therefore requires the least packaging). I guess you also need to consider the relative orientations of the stacks - long end to long end or short end to short end. When filled, what is the weight of the paper in the current-sized box?_____pounds <em>10*5=50 lb </em>

I might have not answered all parts of the question but I answered the ones I know (lol)

Hope that was helpful.Thank you!!!

What the answer question
Ilya [14]

Answer:

<h2>Surface area = 373.66</h2><h2>Step-by-step explanation:</h2>

T.S.A = \pi r(r+l)\\l = 10mm\\r = 7mm\\\\T.S.A = 3.14 \times 7(7 + 10)\\= 21.98(17)\\T.S.A = 373.66\\\\T.S.A =  373.66
