4( a + 2b ) = 4a + 4*(2b) = 4a + 8b;
3( 2a - b ) = 3*(2a) - 3b = 6a - 3b;
3( 2a - b ) + 6a - 7b = 6a - 3b + 6a - 7b = 6a + 6a -3b -7b = 12a - 10b;
Finally, 4a + 8b = 12a - 10b;
8b + 10b = 12a - 4a;
18b = 8a ;
9b = 4a.

If
vitfil [10]

Answer:

x =  \frac{1}{e}

Step-by-step explanation:

f(x) = {(lnx)}^{2}

f1st(x) =  \frac{2 lnx }{x}  = 0

x   <  1 \:  \:  f1 < 0 \:  \: de creasing

f2nd(x) =  \frac{2 - 2 lnx}{ {x}^{2} }  = 0

x  <  e \:  \: f2 > 0 \:  \: concave \: up

So x<1 is the condition which contains x=1/e

I’m really stuck on this ☹️
fgiga [73]

Answer:

2 adults and 2 senior citizens.

Step-by-step explanation:

There are 8 children, which means we need to take the number that represents the children from the graph which is 4 and multiply it by the 8 children going.

1. 4x8=32

So we have found the total for the 8 children, however there are 4 spots left

We take the total from the #1 and add 2 adults and 2 senior citizens.

32+6+6+3+3=50

We then come to the conclusion of 2 adults and 2 seniors.

Factor the expression.<br> x^3+8
Aneli [31]
X^3+8
= x^3+2^3

<span>a^3 + b^3 = (a + b)(a^2 – ab + b^2)</span> 

so

x^3+8 
= x^3+2^3
= (x+2)(x^2-2x+2^2)
= (x+2)(x^2-2x+4)
