Answer 1

@ivettef365

Answer 2

is the 2 in x2 an exponent (x^2)?

Answer 3

yes

Answer 4

x^2+x+8=x^2+2x+5

Answer 5

because both are equal to "y", they are equal to each other

Answer 6

5,8

Answer 7

x^2+x+8=x^2+2x+5
-x^2 -x^2
x+8=2x+5
-x -x
8=x+5
-5 -5
x=3

Answer 8

x=3. where did you get 5,and 8?

Answer 9

3,20 ?

Answer 10

didnt mean to say that

Answer 11

lol okay

Answer 12

then you plug in the x variable to both equations idk if it is 20 but let me check for you

Answer 13

y=3^2+3+8
y=9+3+8
y=20

Answer 14

first one seems good, let me check the next

Answer 15

thank you :)

Answer 16

y=3^2+2(3)+5
y=9+6+5
y=20

Answer 17

so your answer is (3,20) you were correct good job :D
