Answer:
<h2>
first piece: 5 in</h2><h2>
second piece: 10 in</h2><h2>
third piece: 32 in </h2>
Step-by-step explanation:
x - the length of the <u>first piec</u>e
2x - twice the length of the first piece (the length of the <u>second piece</u>)
6x - six times the length of the first piece
two inches more:
6x+2 - the length of the <u>third piec</u>e
first + second + third = 47 in {total length of the pieces of steel}
x + 2x + 6x + 2 = 47
9x + 2 = 47
9x = 45
x = 45:9
x = 5 in
first piece: 5 in
second piece: 2×5 = 10 in
third piece: 6×5 + 2 = 30 + 2 = 32 in
Answer:
2sqrt(10)
Step-by-step explanation:
radical 40
I rewrite this as sqrt(40) It means the same thing
sqrt(40)
sqrt(4*10)
We know that sqrt(a *b) = sqrt(a) sqrt(b)
sqrt(4) sqrt(10)
2sqrt(10)
