Answer:
8
Step-by-step explanation:
Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):
a^2+b^2=c^2
we can find that 3=a and 29=c
3^2+b^2=29^2
9+b^2=841
b^2=832
b=
b=8
That is the height that the ladder will reach
it means when x =0
so 6*0+12y=60
12y=60
y=5
2
Step-by-step explanation
4(6/10-1/5)+0.4
4(2/5+2/5)
8/5+2/5
