Help me on this please
lakkis [162]

Answer:

5 miles.

Step-by-step explanation:

The Pythagorean theorem a^{2}+b^{2} =c^{2} will find any side length of a perpendicular triangle when two sides are known.

We substitute for a, the shortest side, a=3 and for b, the longer side, b=4 to find the slanted hypotenuse c.

a^{2}+b^{2} =c^{2} \\3^{2}+4^{2} =c^{2} \\9+16=c^{2}\\25=c^{2}\\5=c

The direct route is 5 miles.

Make x the subject of h = 4(x + 3y) + 2
Stolb23 [73]

Answer:

x= (h-12y-2)/4

Step-by-step explanation:

First expand the brackets so its 4x+12y+2=h

Then subtract 12y and 2 from both sides

This maxes 4x=h-12y-2

then divide by 4

so its x= (h-12y-2)/4

(you can simplify if you want you dont need to)
