Answer:
The volume of a rectangular prism is
V = l · w · h
V= 252 cm3
h= 3 cm
l=5+W
W=x then l=5+x
V=(5+x)*x*3=252
3x^2+15x=252 cm3
the equation that models the volume of the tray in terms of its width, x, in centimeters.
3x^2 +15x=252 cm3
for width=7.5 cm
3x^2 +15x=3*(7.5) ^2+15*7.5= 281.25 cm3
281.25>252
it is not possible that the width is 7.5 cms
Step-by-step explanation:
Answer:
y = -4/3x +8
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
4x+3y = 24
Subtract 4x from each side
3y = -4x+24
Divide each side by 3
y = -4/3x +24/3
y = -4/3x +8
Step-by-step explanation:
with ABCD and ABDE being parallelograms, this means a indicated by the marks
AB = ED = CD
and with BD = DF that means that the line segments BF and CE are intersecting each other at their midpoint.
so they represent a pair of diagonals of a parallelogram, which makes BCFE a parallelogram.
