18
First you want to change the 20% into a decimal which is .20
Next you want to multiply 90 by .20 because that will give you the answer for 20% of 90
90x.20=18
Hope that helps

Solution given:
b=9 base side of isosceles triangle
a=
1) 2/4 = 1/4 + 1/4
2) 4/6 = 1/6 + 1/6 + 1/6 + 1/6
3) 3/5 = 1/5 + 1/5 + 1/5
4) 3/3 = 1/3 + 1/3 + 1/3
5) 7/8 = 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8
6) 6/2 = 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2
7) 5/6 = 1/6 + 1/6 + 1/6 + 1/6 + 1/6
8) 9/5 = 1/5 + 1/5 + 1/5 + 1/5 + 1/5 + 1/5 + 1/5 + 1/5 + 1/5
9) 8/3 = 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3
10) 1/2 * 8 = 8/2 = 4
11) Unit fractions are fractions where its numerators are 1 and its denominators are positive integer. example: 1/2 ; 1/3 ; 1/4
12) D.) 5/2 = 5 * 1/2
Answer: The answer is (x+2)(x-4)(x-4)
Or as a short form you can write it as 
Step-by-step explanation:
Answer is very lengthy but I am 100% sure that's the correct answer
The function’s value when x = −1 will be C. g(−1) = 1.
<h3>How to calculate the value of the function?</h3>
It should be noted that that a function is simply used to show the relationship that exists between the variables.
There's a 2-column table with 5 rows. The first column is labeled g of x with entries negative 3, negative 2, 0, 2, 3. The second column is labeled f of x with entries.
The. function is x³ + 6x² + 12x + 8.
= x³ + 6x² + 12x + 8.
= (-1)³ + 6(-1)² + 12(-1) + 8
= -1 + 6 - 12 + 8
= 1
Therefore, the correct option is C.
