My brain died so i forgot

Area=

Step-by-step explanation:

area=length times width

squares have the same side length, or length=width

in this problem, the side length of the square is

therefore, length=width=

the length is increased by 11 to make a rectangle

therefore, the new length is

the width stays the same, it is still

therefore, the area of the rectangle is length X width=(a+11)*a

Area=(a+11)(a)

use distributive property ()

Area=(a)(a)+(11)(a)

Area=

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

all it means is function 3
