V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in
V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3
2.5 is your answer because first we divide the numbers then subtract 2 from both sides and simplify
8 goes into 153 19 times.
4x^2-5x-21 is of the form ax^2+bx+c, a quadratic equation.
so b in this case is -5
Your answer is: y=5
Here are the steps:
<span>4=2/9(4y-2)
=2/9(4y-2)=4
=9*</span>2/9(4y-2)=4*9
=2(4y-2)=36
=2(4y-2)/2=36/2
=4y-2=18
=4y-2+2=18+2
=4y=20
=4y/4=20/4
=y=5
