Answer:
D2=21/24 mile
Step-by-step explanation:
Her it is not specified if it is base or height, it only talks about dimensions, so let's work with dimensions
A=1/12 
D1=4/21mile, D2=?
Area of a triangle 
A=((D1*D2)/2) → 2A=D1*D2 → D2=2A/D1 so D2=(2*1/12)/(4/21) =(1/6)/(4/21) = (1*21)/(6*4)=21/24 mile
Answer:
2800000
Step-by-step explanation:
10^6 means 1000000
2.8 x 1000000 = 2800000
we can always find the slope of any line by simply using two points on the line, say let's use (3,4) and (-1,2)

m<E=45.5 m<F=45.5
this is question 8 can't see question 9
