answer is 18
Step-by-step explanation:
use Pythagoras theorem with is a²+b²=c²
if u draw the ladder against the wall you'll get a right triangle .
c is hypotenus which is the longest side of the triangle so it is 30
so you'll get 24²+b²=30²
rearrange to b²=30²-24²
you'll get b=
therefore that is 18
hope you understood :)
Answer: -8
Step-by-step explanation:
1. Combine like terms.
-x - 3 = (x - 3x ) + ( 5 - 16)
2. Simplify.
-x - 3 = -2x - 11
3. To balance the equation, add 2x on both sides.
-x - 3 + 2x = -2x - 11 + 2x
4.
x - 3 = - 11
Solve for x, which gives you -8.
