Answer:
9 units
Step-by-step explanation:
To find the missing value of the base, you have to use the formula to find the area of a parallelogram. Here is how you should think about this problem step-by-step:
1. a = b x h
2. 135 = b x 15
3. 135/15 = b
4. 9 = b

Answer: x=-1 and y= -3
Step-by-step explanation:
Solve for x, x+y=-4
Minus y from both sides so it'll be X=-y-4
Now substitute -y-4 in x-y=2 and solve for y
-y - 4 -y=2
Add like terms, -2y - 4=2
Add 4 to both sides -2y=6
Divide both sides by -2
y= -3
Substitute -3 in x=-y - 4
x=-(-3) - 4
- × (-3)= 3
3 - 4= -1
x= -1
