Answer:
D.$79.89
Step-by-step explanation:
Cost of one yard of fabric = $6.99
Length of fabric bought = 8 yards
Cost of one bag of polyester filling = $7.99
Number of bags of polyester filling bought = 3
Total cost of fabric =
Total cost of polyester filling =
Total cost of materials bought = Total cost of fabric + Total cost of polyester filling
Total cost of materials bought is .
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2

Answer:
35
Step-by-step explanation:
Given
n (A) = 15
n (B) = 20
Students who do not like any subject = 5
Hence, number of students who would like either both or either of the two subjects = 60-5 = 55
n (A or B) = n (A) + n (B) - n (A and B)
Number of students linking both the subjects
55 - 15-20
= 55-35 = 20
Number of students linking only one subject = 60-20-5 = 35
