<span>2x - 5/5 I do believe, sorry if I'm wrong. I got the answer on Tiger.com, that should help you with most of the math you have. Hope this helped!
</span>
<span>So, what you want is the biggest square that can evenly tile a space 240*300. The biggest possible number that can divide 240 and 300. Does that ring any bells? Maybe you should divide 240 and 300</span>
1/3=4/12
1/4=3/12
The common denominator for both fractions is 12. For the 1/3 fraction, you multiply numerator and denominator by 4. For the 1/4 fraction you multiply numerator and denominator by 3
The answer is: " 32a² − 24a − 8 " .
__________________________________________________
Given:
__________________________________________________
(8a − 8)(4a + 1) ; Let us expand this expression using the: "FOIL" method.
___________________________________________________
"FOIL" stands for "<u>F</u>irst terms, <u>O</u>uter terms, <u> I</u>nner Terms, <u>L</u>ast Terms" ;
in that order.
___________________________________________________
Basically:
_______________________________________________________
(a + b)(c + d) = ac + ad + bc + bd ;
in which the:
<u>F</u>irst term is: "ac" ;
<u>O</u>uter term is: "ad" ;
<u>I </u>nner term is: "bc" ;
<u>L</u>ast term is: "bd " .
__________________________________
So; we have (given):
(8a − 8)(4a + 1) ;
__________________________________________________
Let's take the "<u>F</u>irst, <u>O</u>uter, <u> </u><u>I</u>nner, and <u>L</u>ast terms" ; as follows:
__________________________________________________
<u>F</u>: (8a)*(4a) = 32a² ;
__________________________________________________
<u>O</u>: (8a)*(1) = 8a ;
__________________________________________________
<u>I </u>: (-8)*(4a) = -32a ;
__________________________________________________
<u>L</u>: (-8)*(1) = -8
__________________________________________________
Now, let us write out these terms:
__________________________________________________
32a² + 8a − 32a - 8 ;
__________________________________________________
Now, combine the "like terms" in this expression; to simplify:
+ 8a − 32a = -24a ;
__________________________________________________
and rewrite the simplified expression ; which is:
__________________________________________________
32a² − 24a − 8 .
______________________________________________________
The answer will be (B) -9 because since the angles are equal, the two sides must be equal also.
Therefore
x+16=7
And then
x= 7-16
x=-9
