Answer:
18
Step-by-step explanation:
= -4 x (-5) - 2
= 20 - 2
= 18
-5x +3 =18
Subtract 3 from each side
-5x= 15
Divide by -5
x= -3
to solve you must dive 14 by 12 then simplify to the nearsest tenth.
Answer:
20 feet
Step-by-step explanation:
Remember the Pythagorean theorem,
x^2 + y^2 = n^2
in this case
x= 16
y = 12
so substitute back into the equation
16^2 + 12^2 = n^2
256 + 144 = n^2
400 = n^2
sqrt ( 400) = n
20 = n
