Answer:

the answer I got is 8 but I'm not sure if it's right though

Step-by-step explanation:

step1) you count each side of the last layer E.g the first line :7+5+5=17 then, 5+7+6=18 and 7+8+3=18

step2) from this u can c tat both sides(7,8,3) and (5,7,6) have the same amount of number which is 18

step3) so from this , what I'm doing is basically assuming tat the line (7,5,5) and (3,?,6) will add up to the same number which is 17

step4) thus we use 17 - 6 - 3 =8

x(x-24)+2(x-24)
(x+2)(x-24)

Solve by grouping if you are able to find distinct factors that multiply to the last term and add to the middle term...this method is rather easy with easy to manage numbers. Complete the square if you cannot find distinct factors that multiply to the last term and add to the middle term. Completing the square helps when the equation is in the form of a parabola.

How do you find the complete square of a math problem
dolphi86 [110]

Step-by-step explanation:

I am not sure what exactly you mean.

do you mean the complete square of an expression or

term ?

if so, then by multiplying this term by itself, and that means in general, every part is multiplied by every part and the part results are added considering the signs involved.

e.g.

squaring a+b

(a+b)(a+b) = a×a + a×b + b×a + b×b = a² + 2ab + b²

remember that multiplication and addition are commutative (you can flip the right and left sides with each other and still get the same result : a+b = b+a, a×b = b×a).

squaring a-b

(a-b)(a-b) = a×a + a×-b + -b×a + -b×-b = a² - 2ab + b²

remember that

+×- = -×+ = -

-×- = +

+×+ = +

a more complex example ?

squaring a-b+c

(a-b+c)(a-b+c) =

= a×a + a×-b + a×c + -b×a + -b×-b + -b×c + c×a + c×-b + c×c =

= a² - 2ab - 2bc + 2ac + b² + c²

2- log 6-log 9<br> In condensing
Tju [1.3M]

Answer:

\log(150)

Step-by-step explanation:

We want to rewrite the following as a single logarithm:

2 -  log(6)  -  log(9)

We introduce logarithm in the first term to get:

2  \log(10)  -  \log(6)  -  \log(9)

Recall that:

log(a)  -   log(b)  = \log \frac{a}{b}

We apply this property to get:

2 log(10)  -  log( \frac{6}{9} )

This gives:

log( {10}^{2} )  -  log( \frac{6}{9} )

log( {100})  -  log( \frac{2}{3} )

log( \frac{100}{ \frac{2}{3} } ) =  log( \frac{300}{2} )  =  log(150)
