Answer:
4x^2-16
Step-by-step explanation:
2x times 2x =4x^2
2x times -4 =-8x
4 times 2x =8x (-8x and 8x cancle eachother out)
4 times -4 =-16
Remember
P=2(l+w)
w=wdith
l=legnth
w is 3/4 legnth
w=3/4l
P=50 when l+2 and w+2
so
50=P=2(l+2+w+2)
w=3/4l, so sub
50=2(l+2+3/4l+2)
divide everybody by 2 to ge rid of nasty parenthasees
25=l+2+3/4l+2
25=1 and 3/4l+4
minus 4
21=1 and 3/4l
21=7/4l
times 4 both sides
84=7l
divide by 7
12=l
sub
w=3/4l
w=3/4(12)
w=9
legnth=9
width=12
