nikdorinn [45]

Answer:

<h2>A. 4 in</h2>

Step-by-step explanation:

Collinear points are points that lies on the same straight line. If the points E, F and G are collinear points, then the three points lies on the same straight line.

If E is between F and G, the FE+EG = FG

EG = FG - FE

Given FE = 3 in and FG = 7 in

On substituting into the expression above to get EG;

EG = 7in - 3in

EG = 4in

Hence the length of EG is 4in

8. Find GH,<br> E<br> 3-4<br> HY<br> -<br> H<br> 2<br> 3x - 4<br> G<br> SI<br> F<br> 9x - 59<br> D
Ostrovityanka [42]

Answer:

GH= 47

Step-by-step explanation:

2(3x - 4) = 9x - 59

6x - 8 = 9x - 59

6x - 9x =  - 59  + 9

\cfrac{ - 3x}{ - 3}  =  \cfrac{ - 51}{ - 3}

x = 17

gh = 3(17)  - 4

51 - 4

= 47
