Answer:
(3x+7y)(3x−7y)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=3x and b=7y
Umm if you need more details just ask.
Hope this helps .-.
Note: <em>It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.</em>
Answer:
140 cm of the original piece is left after Joe cuts three pieces.
Step-by-step explanation:
Given the piece of string
As we know that
so the length of a piece of string = 350 cm
As joe cuts three pieces from it, and each 70 cm long.
so the total length of three pieces which were
cut by joe = 70cm + 70cm + 70cm = 210 cm
So, subtracting the total length of the three pieces that were cut from the total length of the string:
350 cm - 210 cm = 140 cm
Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.
Answer:
Step-by-step explanation:
x+2/x = 3/2
(x + 2)*2 = 3*x {cross multiplication}
2x + 4 =3x
2x-3x = -4
-x = -4
x = 4
3 and 1/8 times 3 and 1/4=25/8 times 13/4=325/32=10 and 5/32
3 and 1/8 and 3 and 1/4
Answer:
15
Step-by-step explanation:
(-2,3)-x1,y1
6,r -x2,y2
slope(m)=3/2
m= y2-y1/x2-x1
3/2= r-3/8
r=15
