Answer:
13 cm
Step-by-step explanation:
Using the Pythagoras therorem
We get the answer as
Root of (12squared +5squared)
Root of (144+25)
Root of 169
=>13 cm
<span>The ordinate is three more than twice the abscissa
</span>Ordnate: y; Abscissa: x
y=3+2x
x=-1→y=3+2(-1)=3-2→y=1→(x,y)=(-1,1)
x=0→y=3+2(0)=3+0→y=3→(x,y)=(0,3)
x=-1/3→y=3+2(-1/3)=3-2/3=(3*3-2)/3=(9-2)/3→y=7/3→(x,y)=(-1/3,7/3)
Answer: Option <span>A) {(-1,1),(0,3),(-1/3,7/3)}</span>
Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:

<em>multiply both sides by 8</em>
