Distribute and simplify: 7(2x-4) + 2(3x+1) a.20x+26 b.20x-26 c. 14x-28 d. 6x+2 evaluate the expression 4y^2 - 2x / 7 + 2y for x=7 and y=2 a. 2 b. 4 2/7 c. 5 d.18

7(2x - 4) + 2(3x + 1)   Distribute/multiply 7 into (2x - 4), and multiply 2 into (3x + 1)

14x - 28 + 6x + 2   Combine like terms

20x - 26

Your answer is B

x = 7

y = 2

Plug in the numbers into the variables

4(4) - 2 + 4

16 + 2

18

Your answer is D

109 trust me

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
