Troy cut a 100 foot rope into 3 pieces. The first piece is 43 foot long. The second piece is at least 22 feet long, but no great
Inessa05 [86]

Answer:

x=4

Step-by-step explanation:

Let he first piece be x the second be 3x and the very last one be 7x + 2

 

Add all the pieces together and you ought to get the length of the rope which is 46 ft

 

So your equation would be

 

x + 3x + 7x + 2 = 46

 

11x = 44

 

x = 44 / 11

 

x = 4

 

so the 3 pieces are 4 , 12 and 30ft

The arc shown is 140 degrees. Find the measure of angle 1.
Elodia [21]

The angle subtended by two chords is half the enclosed arc measure.   If we imagine one of the chords getting shorter and shorter this remains true.  In the limit the shrinking chord becomes a tangent, and the angle is still half the arc measure.

Answer: 70 degrees

For what values of x'is x2 + 2x = 24 true?
Paladinen [302]

Answer:

\boxed{Values \: true \: of \: 'x' \: for \: equation \: {x}^{2} + 2x = 24 \: is \: -6 \: and \: 4}

Step-by-step explanation:

=  >  {x}^{2}  + 2x = 24 \\  \\  =  >  {x}^{2}  + 2x - 24 = 0 \\  \\  =  >  {x}^{2}  + (6 - 4)x - 24 = 0 \\  \\  =  >  {x}^{2}  + 6x - 4x  -  24 = 0 \\  \\  =  > x(x + 6) - 4(x + 6) = 0 \\  \\  =  > (x + 6)(x - 4) = 0 \\  \\  =  > x + 6 = 0 \:  \:  \:  \:  \:  \:  \:  \: and \:  \:  \:  \:  \:  \:  \:  \:  \: x - 4 = 0 \\  \\  =  > x =  - 6 \:  \:  \:  \:  \:  \:  \:  \:  \:  \: and \:  \:  \:  \:  \:  \:  \:  \:  \: x = 4

Values true of 'x' for equation x² + 2x = 24 is -6 and 4
