A^2 + b^2 = c^2
3^2 + 8^2 = c^2
9 + 64 = c^2
73 =c^2
take the square root of each side
c= 8.544
Answer:
Step-by-step explanation:
If slope of two lines are equal, then they are parallel lines.
If product of the slope of two lines is (-1), then they are perpendicular lines.
C) y = x + 2
Slope m1 = 1
y = -x + 3
Slope m2 = -1
m1 * m2 = 1 * (-1) = -1
These are perpendicular lines.
D) y = 3x + 2
Slope = m1 = 3
y = 3x - 2
Slope = m2 = 3
Slopes are equal. So, they are parallel lines.
E)y= 3
This line is parallel to x -axis.
x = 4
This line is parallel to y-axis.
So, both lines are perpendicular to each other.
F) y = x + 8
slope m1 = 1
y = -x + 3
Slope = m2 = -1
M1 * m2 = 1 * (-1) = -1
So, These are perpendicular lines
Answer:
-10 would be your answer.
Answer:
The answer would be 16b^2 - 14b + 3
Step-by-step explanation:
In order to find this, we simply need to group the terms by their variable values. We will start with the b^2 terms.
5b^2 + 24b^2 - 13b^2 = 16b^2
Now we can use all of the b terms.
-5b - 8b - b = -14b
And finally, we'll do all the constants.
4 - 1 = 3
Using all three of these together will give us the simplified form.
