Answer:

1. Squaring binomials of the form/ square of a sum

2. The answer is P= 50x

Solution: 15x(2)+10x(2)= 30x+20x = 50x

3. X=2 I used transposed

Solution: 9x+9=27

9x=27-9

9x/9=18/9

x= 2

4. A-andrea=22, G-grace= 12

solution: A= 10G

A-10G=0 eq 1

(A-10)=(G-10)+2

A-10-G= 0 eq 2

eq1 - eq2

A-10G-[A-10-G]=0

A-10G-A+10+G=0

-G+10=0

G=10

A=10G

A=20

PRESENT TIME

A= 20+2

A=22

G= 10+2

G= 12
