Answer:
<u>3</u><u>z</u><u>^2 + 3z - 6 </u>=0
3
3 (z^2 + z -2) = 0
3(z+2)(z - 1) = 0
z + 2-2 = 0 - 2
z = -2
z - 1 + 1 = 0 + 1
z = 1
Step-by-step explanation:
- factor out the GCF (3) and divide everything by it, and then set it equal to zero.
- since you have a degree of 2, factor it into two binomials that start with the square root of the first term and end with the square root of the second term.
- 3=0 is extraneous solution so we leave it, then we set each binomial equal to zero to solve for z.
note: your solutions is based on the degree or the exponent of the polynomial or the function.

Step-by-step explanation:
You would do 26/60 and turn it into a percentage (43.33333333%)
In order to accurately answer any fraction, it is best to have a common denominator (bottom of the fraction)
Since in
, 100 is the denominator, you need to make the other fraction with the same denominator
So Multiply
by <u />
So
or
You can do this another way which involves the opposite way of multiplying which is by dividing
Since you have to get a common denominator to measure accurately no matter what, you can divide
One thing to know is that when dividing fractions, both the denominator and numerator have to be divided by a factor to be divided and result in a whole number
÷
=
So just have to multiple
⇒
⇒
The results are the same

Answer:
4 ounces
Step-by-step explanation:
To solve this problem, lets first take into account that 1 cup is equal to 8 ounces. Now, we need to cross multiply. Lets input the values 1, 8, and 0.5 (0.5 is 2/4) as shown below:
Next we cross multiply. We multiply 1 and x, and we multiply 8 and 0.5.
Now, if we simply put the variable x and the number 4 into an equation, we get:
4 ounces is the answer.
