Help ASAP please! Idk what to do

see below

Step-by-step explanation:

(1.3) ^ 2= (1.3) (1.3) = 1.69

(1.4) ^ 2= (1.4) (1.4) = 1.96

(1.5) ^ 2= (1.5) (1.5) = 2.25

2 is close to 1.96 so the square root of 2 is close to 1.4

Step-by-step explanation:

2x + 3y = 18

2x - 3y = -6

+

4x = 12

x = 12/4

x = 3

2x + 3y = 18

2(3) + 3y = 18

6 + 3y = 18

3y = 18 - 6

3y = 12

y = 12/3

y = 4

Solution → (x,y) = (3,4)
