Consider the following 8 numbers, where one labelled X is unknown.

Effectus [21]

Answer:

$55,-3$

Step-by-step explanation:

$We\ are\ given\ that,\\There\ are\ eight\ numbers\ in\ the\ data :\\17,18,24,x,44,48,42,4\\Where\ the\ value\ of\ x\ is\ what\ we\ need\ to\ find.\\Range\ of\ the\ data=51\\Hence,\\We\ know\ that\ the\ range\ is\ the\ difference\\ between\ the\ highest\ observation\ and\ the\ lowest\ observation\ in\ the\ data.\\We\ may\ know\ see\ two\ cases\ of\ evaluating\ x\ when:\\1. x\ is\ the\ highest\ observation\ in\ the\ data\ or\ x>48.\\Highest\ observation\ =x\\Lowest\ observation=4\\Hence,\\$

$As\ range=51,\\x-4=51\\x=51+4\ [Adding\ 4\ on\ both\ the\ sides]\\x=55 \\2. x\ is\ the\ lowest\ observation\ or\ x$

The expression n2 + n represents the total number of blocks used in the nth figure of a pattern. Use the equation n2 + n = 56 to

Brrunno [24]

We have to solve this quadratic equation $n^{2}+n=56$ for n to get <em>which figure has 56 blocks</em>.

$n^{2}+n=56\\n^{2}+n-56=0$

For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>

<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>

<em> $n^{2}+n-56=0\\(n+8)(n-7)=0\\n=-8, 7$ </em>

<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>

Our answer is 7.

ANSWER: The 7th figure has 56 blocks.

The area of a triangle is 108 square units. If the base is 18 units,what is the height?

aleksandrvk [35]

Answer:

Step-by-step explanation:

Area of a triangle = 1/2(base)(height)

108 = 1/2(18)(height)

108 = (9)(height)

divide both sides by nine

The height of the triangle is 12 units
