Because h(x)=f(2x+1), h(1)=f(2*1+1)=f(3)
find f(3) in the table, the answer is 6, c is correct.

Step-by-step explanation:

Easy:)

$7)4a^{8}b^{12} \\8)25x^{6}y^{8}\\9)x^{9}y^{9}$ × $xy^{2}$

= $x^{10}y^{11}$

$10)a^{3}$ × $a^{8}b^{4}$

= $a^{11}b^{4}$

$11)4a^{2}b^{4}$ × $9a^{4}b^{2}$

$=36a^{6}b^{6}$

Have a nice day! :)

$750 + s x 4% = $2,500 | - $750

s x 4% = $1,750 | : 4%

s = $43.750

Answer:

true

Step-by-step explanation:

let the vertex of the triangle be A(x1, y1), B(x2, y2), C(x3, y3) .

the centroid of the triangle will be ( $\frac{x1+x2+x3}{3}$ , $\frac{y1, y2, y3}{3}$ ).

cordinate of mid point of AB ( $\frac{x1+x2}{2},\frac{y1+y2}{2}$ )
