Answer:
5
Step-by-step explanation:
5z +9 - 4z
- All you have to do is substitute the value of z instead of the variable.
5(-4) + 9 - 4(-4)
-20 + 9 + 16
-11 + 16
5
The length of the base is 27 and the length of the height is 17.
To find the answer, you need to add up each side twice and set it equal to 88.
x-6+x-6+x+4+x+4=88
That is equal to: 4x - 4 = 88
Add 4 to both sides: 4x = 92
Divide by 4: x = 23
Now plug 23 in for x:
Base: 23 + 4 = 27
Height: 23-6=17
x to both sides
2 = 3x + 1
subtract 1 from both sides
1 = 3x
divide both sides by 3.
x = 1/3
plug this guy into one of the equations to get y = 5/3.
