The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14
As We can see that point J is on (-2,5) and L is on (-2,-2)
So we know that distance cannot be in negative, thus
Distance between J and L =5+2=7 units
JL=7
Answer:
y = ⅓x
Step-by-step explanation:
Let's find m.
m = y/x
Using the point on the line, (3, 1),
m = ⅓
Substitute m = ⅓ into y = mx
This, the equation that describes the relationship would be:
y = ⅓x
The missing length is 12km (i never promised anything xd)
Answer:
53°
Step-by-step explanation:
17² = 18² + 20² - 2(18)(20) cos Q
289 = 324 + 400 - 720 cos Q
289 = 724 - 720 cos Q
-435 = -720 cos Q
0.6042 = cos Q
Q = 52.83
