Question 1
olga_2 [115]

Step-by-step explanation:

(7r+5s)^2

use the pattern

(a+b)^2=a^2+2ab+b^2

(7r+5s)^2=(7r+5s)(7r+5s)

Apply FOIL method to multiply the parenthesis

(7r+5s)^2=(7r+5s)(7r+5s)

(7r+5s)(7r+5s)\\49r^2+35rs+35rs+25s^2\\49r^2+70rs+25s^2

Compare the expression with (a+b)^2=a^2+2ab+b^2

The value of a=7r and the value of b=5s

Answer :

a=7r ,  b=5s

Sandra rolls 2 fair dice.<br> What is the probability of both dice showing a different number?
IRINA_888 [86]

Answer:

Each one has 3 even and 3 odd numbers.

For the first one to be even there is a 3/6 probability, which reduces to 1/2.

The probability of the second one being even is also 1/2.

The probability of both being even would be 1/2 x 1/2 = 1/4 probability
