Area= length*width
115= x * 5
115/5 = x
23 = x
So the length will be 23 cm.
What are the solutions of this system of equations? Select all that apply. y = x2 − x − 3 y = −3x + 5
-75 is the answer for the tenth term
According to google, the red marks mean those two lines are the same length. If that's the case, we know that x is the angle in both corners of the lower triangle. We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40. That leaves 140 for the rest. Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees. It is divided in two parts, the lower one of which we just found to be 20. So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees
Y= -9(10)+10
y= -90+10
y=-80
Answer: y= -80
