Answer:
Y=60
Step-by-step explanation:
S+Y=90
S=(2*Y)-90
Y+2Y-90=90
3Y=180
Y=60
Plug back into S+Y=90
S+60=90
S=30

Answer:
Perpendicular
Step-by-step explanation:
Parallel lines mean lines that have same slope but since both equations have different slopes which you can check by looking at m-value in y = mx + b. In this case m1 or first slope is -4/3 and m2 or second slope is 3/4.
Perpendicular means that both lines are reciprocal to each other. This means the perpendicular condition is or satisfies ![\displaystyle \large{m_1m_2 = -1 \longrightarrow m_1 = -\frac{1}{m_2} \longrightarrow m_2 = -\frac{1}{m_1}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%7Bm_1m_2%20%3D%20-1%20%5Clongrightarrow%20m_1%20%3D%20-%5Cfrac%7B1%7D%7Bm_2%7D%20%5Clongrightarrow%20m_2%20%3D%20-%5Cfrac%7B1%7D%7Bm_1%7D%7D)
We have m1 = -4/3 and m2 = 3/4.
Therefore, -4/3 * 3/4 = -1 thus both lines are perpendicular to each other as it satisfies m1m2 = -1 condition.
X would be 4 so the answer is B
Since the problem is already factored for you all you have to do is set each of the factor set to zero. Because length cannot be negative, The width is going to be equal to 10cm
Set the equation up no with 10 plugged in for (w) in 240=(l)(10)
Therefore length is 24
