Answer:8
Step-by-step explanation: Do 30 times 8
Answer:
x = -30
y = -20
Step-by-step explanation:
x - 12y = 210..... (I)
x - 6y = 90..... (II)
Subtract equation (II) from (I)
- 12y - (-6y) = 210 - 90
-12y + 6y = 120
-6y = 120
Divide through by -6y
Therefore, y = -20
Substitute y = -20 in equation (II)
x -6 (-20) = 90
x + 120 = 90
x = 90 - 120
x = -30

Answer:
x^2−64
Step-by-step explanation:
(x+8)(x−8)
=(x+8)(x+−8)
=(x)(x)+(x)(−8)+(8)(x)+(8)(−8)
=x^2−8x+8x−64
=x^2−64
