How to factor (16+2x)(12+2x)=396

2 answers:

8 0

First, you have to combine all the like terms such as both the 2x’s and 16 and 12 which will give us 28+4x=396. Then you subtract 396 from 28 which is 368. You want the variable x to be alone so you divide 368 by 4 which gives you 92.

Step-by-step explanation:

$(16 + 2x)(12 + 2x)$

$= 4x^{2} + 24x + 32x + 192 = 396$

$4x^{2} + 56x - 204$

this then becomes the answer of

$4(x + 17) \times (x - 3)$

1) 144 ft

2) 292.5 ft

Step-by-step explanation:

1) SA= lw+ 4(1/2( <em>l </em>)h)

SA=6*6+ 4(1/2( 6 )9)

SA=36+ 4(1/2( 6 )9)

SA=36+ 4( 3*9 )

SA=36+ 4( 27 )

SA=36+ 144

2) SA= 1/2( / )h+ 3(1/2( <em>l </em>)h)

SA=1/2( 15 )13+ 3(1/2( 10 )13)

SA=7.5*13+ 3 ( 5*13 )

SA=7.5*13+ 3 ( 65 )

SA= 97.5+ 3 ( 65 )

SA=97.5+ 195

SA= 292.5

In-s [12.5K]

Answer: 0.00153

Step-by-step explanation:

Given: An experiment consists of dealing 7 cards from a standard deck of 52 playing cards.

Number of ways of dealing 7 cards from 52 cards = $^{52}C_7$

Since there are 13 clubs and 13 spades.

Number of ways of getting exactly 4 clubs and 3 spades= $^{13}C_4\times\ ^{13}C_3$

Now, the probability of being dealt exactly 4 clubs and 3 spades

$=\dfrac{^{13}C_4\times\ ^{13}C_3}{^{52}C_7}\\\\\\=\dfrac{{\dfrac{13!}{4!(9!)}\times\dfrac{13!}{3!10!}}}{\dfrac{52!}{7!45!}}\\\\=\dfrac{715\times286}{133784560}\\\\=0.00152850224271\approx0.00153$

Hence, the probability of being dealt exactly 4 clubs and 3 spades = 0.00153
