Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them
2x²+9x-16x-72
2x²-7x-72
16 x w x 8 = 1664
<span>w = 1664 / 16*8 = b) 13 cm</span>
Hello,
Answer A (graph most left)
Intersection is (10/3,-11/3)
y=-2x+3
y=-2-x/2
so -2x+3=-2-x/2
==>3x/2=5 ==>x=10/3
and y=-2*10/3+3=-11/3
