Simplify the following expression: x^2+3x-4/x+2. WILL AWARD BRAINLIEST!!! a. x+1- 6/x+2
b. x+1
c. x+1+ 6/x+2
d. x+5+ 6/x-2

a. she will receive a refund of $278.

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
