Answer: 2a/3 + b/3
Since it has two different variables, there is no final answer. To find the answer, you must first expand the equation and then apply the fraction rule.
Minus z both sides
0=x^2+wx+z
we can use quadratic formula or manually complete the square
let's use quadratic
for
0=ax^2+bx+c

given
0=1x^2+wx-z
a=1
b=w
c=-z



or
Answer:
for perimeter you add all the sides and for area you multiply
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
When numbers are raised to an exponent/power, it means how many times you are multiplying the number by itself.
Follow BEDMAS order. (Brackets, exponents, division/multiplication, addition/subtraction).
Solve inside the brackets of (8^1)^0 first
(8^1)^0 8^1 is 8. (Any number ^1 is itself).
= 8^0 Any number to the power of 0 is 1.
= 1
You can also follow the exponent rule where: 
(8^1)^0 = 8^(1*0) = 8^0 = 1
Y = 0 + 2
Since it is a horizontal line, the slope is m = 0.
For the y-intercept, the line passes through 2 so therefore, the y-intercept is 2 positive.
