The equation to find the length of the longer piece is
x- 12 = 55
Step-by-step explanation:
- A carpenter had two pieces of lumber that totaled in length = 55 feet
- The shorter piece than the longer piece has length of which is = 12 feet
- The longer piece is denoted as= x
- Find x = ?
- The equation can be formed to find the value of x as,
- Longer piece (x) ₋ shorter piece (12) = total length (55)
- Therefore, x ₋ 12 = 55
- the above equation states that
- if you subtract the shorter piece from the total length of the you will get the length of the longer piece.
- therefore,
- if you shift the value of shorter length on the right hand side, you can find the value of x
- so, x= 55 ₋ 12
- value of x = 43
- therefore, the length of the longer piece is 43 feet long.
Answer:
<h2>400 m^2</h2>
Step-by-step explanation:
Area = 30 x 15 - 10 x 5
Area = 450 - 50
Area = 400 m^2

Step-by-step explanation:
to evaluate f(g(x)) substitute x = g(x) into f(x), that is
f(g(x)) = f(x - 1) = 3(x - 1) = 3x - 3
Similarly to evaluate g(f(x)) substitute x = f(x) into g(x)
g(f(x)) = g(3x) = 3x - 1
Answer:
In 286 different ways 10 players can be selected.
Step-by-step explanation:
There are 6 girls and 7 boys in a class. So in total there are 6+7 = 13 number of students in the class.
A team of 10 players is to be selected from the class.
As there is no other conditions are given, we can pick any 10 students from 13 students.
The way we can select 10 players from 13 students is;
= (13 10)
= 13!/10!(13-10)!
= 13!/10! 3!
= (13 × 12 × 11 × 10!)/ 10! 3!
= ( 13 × 12 × 11)/6
= 286
