Answer:
the area of the garden is 9 square kilometers
Step-by-step explanation:
4s=12
s=3
A= 3*3 = 9
Answer:
There are 49 white marbles.
Step-by-step explanation:
w + g = 62 (w = white and g = green marbles).
w = 4g - 3
w - 4g = -3 Subtract this equation from the first equation:
g - (-4g) = 62 - (-3)
5g = 65
g = 65/5 = 13.
So w = 62 - 13 = 49.
Answer:
you can always use sin or cos or tan in these situations
Since the product of the slope is -1, hence the lines are perpendicular
<h3>Parallel and Perpendicular lines</h3>
Two lines are known to be parallel if they have the same slope while if two lines are perpendicular if the product of the slope is -1
Given the coordinates of line 1 passing through (0, 6) and (6, 4), the slope is given as;
Slope = 4-6/6-0
Slope = -2/6
Slope = -1/3
Similarly for the coordinate points (-1, -7) and (1, -1).
Slope = -1+7/1+1
Slope of line 2 = 6/2
Slope = 3
Take the product of the slopes
Slope = -1/3 * 3
slope = -1
Since the product of the slope is -1, hence the lines are perpendicular
