Answer:
12
Step-by-step explanation:
12
4(m-2)=24
4m-8=24 distributive property
add 8 to each side
4m=32
divide each side by 4
m=8
0.98 is already rounded
it may also be asking for 0.980, which is equal but shows the thousandth place
Distance Formula: 
Point 1: (9,0)
Point 2: (5,-8)
D = sqrt[ (5 - 9)^2 + (-8 - 0)^2 ]
D = sqrt[ (-4)^2 + (-8)^2 ]
D = sqrt[ 16 + 64]
D = sqrt(80)
Hope this helps!
