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:
D. A straight line segment can be drawn between any two points
A. Any straight line segment can be extended indefinitely
Step-by-step explanation:
The answer is the number will have to be less than 11 which means that it is a. 9
sorry if it is incorrect.
X=7
after you remove parentheses you do those steps
Anything to the power of 0 is 1 so f(x) =1
Hope this helps :)
