Radical 2x+5 equals x

1. Square both side.

2x+5 equals x square

Move everything to one side.
X square-2x-5=0

Since this time, we can't factor very well. We need to use the quadratic formula.

-b+- square root b square- 4ac divided by 2a

This gives: -(-2)* square root( 4-4(1)(5))/ 2

Notice that we get 2 plus and minus square root of -16.

Which is an imagery/ complex solution.

The value of x could be 2+i4/2 or 2-i4/2

If the standard volume of a
Alla [95]

Answer:

6.7 %

which agrees with answer A in your list.

Step-by-step explanation:

If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :

1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:

0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%

Recall as well that percent error is always expressed as a positive number.

Jafar has a fruit basket with 13 pieces of fruit. He has 1 orange, 5 apples, 4 kiwis, and 2 pears in the basket. He also has ban
mars1129 [50]
<h3>Hello there!</h3><h3>Answer: 1/13</h3>

1/13 would represent the amount of bananas in the basket.

There would be only 1 banana because it would complete he amount of fruits in the basket.

In the basket, we know that there are:

1 orange + 5 apples + 4 kiwis + 2 pears = 12

That would be 12 fruits, but there are suppose to be 13 fruits, which means that the remaining 1 fruit would be a banana.

So, that means that the amount of bananas in the basket is 1 out of 13, or 1/13.

Max wants to run 512 miles to train for track season. If the total length around the track is
GalinKa [24]

Max needs to run 15 laps around the track.

Step-by-step explanation:

Given,

Distance Max wants to run = 512 miles

Length around the track = 34 mile

34 miles = 1 lap

1 mile = \frac{1}{34}\ laps

512 miles = \frac{1}{34}*512

512 miles = 15.06 laps

Rounding off to nearest whole number;

512 miles = 15 laps

Max needs to run 15 laps around the track.

mina [271]
Hey! the answer would be A regular 40-sided polygon has an interior angle equal to:
(40 - 2) (180) /40 = 171 degrees

The interior angle is also the smallest angle that is needed to  rotate the polygon and map it unto itself. So, the smallest degree of rotation needed to map the polygon back to itself is 171 degrees.
