Answer:  1/4, 4/7, 5/8

Step-by-step explanation:  There are three ways:

1.  <u>Convert each to a decimal: </u>

 1/4 = 0.25

 4/7 = 0.571

 5/8 = 0.625

2.  <u>Convert to a common denominator:</u>

 It looks like we can multiply each by a whole number that will result in a denominator of 56:

 1/4 *(14/14) = 14/56

 4/7*(7/7) = 35/56

 5/8 *(8/8) = 32/56

Now they can be directly compared to get the answer.

3.  <u>Estimate the values.  </u>

5/8 is clearly larger than 1/4.  4/7 is somewhere in between.  Therefore, 1/4, 4/7, 5/8

In figure 2, find x if the perimeter is 4. Does each answer make sense? Why or why not?
stealth61 [152]

The value of x is equal to 1.5.

It is required to find x.

<h3>What is quadratic equation?</h3>

Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.

Given that:

So for the triangle, the perimeter would be:

(x^{2} +x+3)+(x^{2} +2x-2)+(x^{2} +2x-9)=4

By solving in above equation, we get

(x^{2} +x+3)+(x^{2} +2x-2)+(x^{2} +2x-9)=4\\\\\\\2x^{2}+5x-8=4\\\\2x^{2}+5x-12=0\\\\2(x + 4)(x - 1.5)=0\\\\ x=-4\\\\ x=1.5

So, we take x= 1.5 and neglect -4 because we can't take negative roots of the quadratic equation.

Hence, the value of x is equal to 1.5.
