Question

Can someone help me solve this problem?

Answer 1

`Answer: Q\ is\ not\ midpoint\ of\ \overline {PR}`

Explanation:

`\displaystyle\\\overline {PQ}+\overline {QR}=\overline {PR}\\5(x+2)+(8x-3)=72`

Expand the parentheses on the left side of the equation:

x(5)+2*(5)+8x-3=72

5x+10+8x-3=72

13x+7=72

13x+7-7=72-7

13x=65

Divide both parts of the equation by 13:

x=5

Hence,

5(5+2)=

5(5)+2(5)=

25+10=

35

8(5)-3=

40-3=

37

35≠37

Answer 2

no

Explanation:

x=5

5(5+2)=35

8(5)-3=37

37 does not equal 35
