Answer:
a) Length = (20 - 2x) inches
Width = (15 - 2x) inches
b) Volume = (20 - 2x)(15 - 2x)x cubic inches.
Step-by-step explanation:
A metalworker makes a box from 15 inches by 20 inches piece of tin by cutting a square with a side length x out of each corner and folding up the sides.
a) So, the length of the box will become (20 - 2x) inches.
And, the width of the box will become (15 - 2x) inches.
b) The volume of the box will be = (Length × Width × Height)
= (20 - 2x)(15 - 2x)x cubic inches. (Answer)
Answer: 2(x-11)
Step-by-step explanation:
The x intercepts were supposed to be x = 3, 7
Let's assume
number of nickels =n
number of dimes =d
we are given
total number of coins =9
so, we get

we know that
1 nickel =$ 0.05
and
1 dimes =$0.10
so, total amount is

we are given
total amount =$2.15
so, we get

so, we get system of equations as
