Rate times time equals distance
X*.8=14.2
Divide both sides by .8
14.2/.8= 17.75
5*( -3.4k ) + 5*( - 7 ) + 3k + 12 = - 17k + 3k - 35 + 12 = -14k - 23 ;
Answer:
by applying Pythagoras theorem;
the ladder(13m) acts as hypotenuse
the wall (12m) acts as height
the distance between the the two is the base
therefore
a² + b² = c²
b²= c²- a²
b²= 169 - 144
b² = 25
√b² = √25
b= 5m
the distance is 5m
The correct answer is D. You can see It is the biggest bar and so you can estimate the correct answer.
