Answer:

B) 4.5

Step-by-step explanation:

The area of the first figure is 10x

The area of the second figure is 6(x+3)=6x+18

To solve, find the x that makes 10x=6x+18

1) 10x=6x+18

2) 4x=18

3) x=4.5

To check work)

1) 10(4.5)=6(4.5)+18

Question~

Rasek [7]

Answer:

B. 1

Step-by-step explanation:

Multiply the first term by $x^a$ , the second term by $x^b$ , the third term by $x^c$ .

The first term becomes:

$x^a/(x^a+x^b+x^c)$

The second term becomes:

$x^b/(x^a+x^b+x^c)$

The third term becomes:

$x^c/(x^a+x^b+x^c)$

Their sum is:

$(x^a+x^b+x^c)/(x^a+x^b+x^c) = 1$

Correct choice is B
