B) the one that has the sides 4 & 8 and 3 & 6.

The length on both of these rectangles are twice as long as the width

one rectangle goes from a width of 4 and its length is doubled to a length of 8
it is similar to the 3 & 6 because the width of 3 is doubled to get the length of 6

hope this helps

5 points<br> Write the polynomial 5x + 2x3 + 8x2<br> 7 in standard form.

artcher [175]

Find the GCF, then factor it out. Finally, simplify each term in the parentheses.

5x + 2x3 + 8x2

$x(\frac{5x}{x}+\frac{2x^3}{x}+\frac{8x^2}{x} )$

$x(5+2x^2+8x)$
