Answer:
4
Step-by-step explanation:
Here you need not completely solve 7992 squared. You can just take the last digit which in this case is 2 and solve for the square of that digit. 2 x 2 = 4. Now if it was a bigger digit which would result in a two digit number when squared you would take the last digit of that number. But, we don't need to do that here since 2 squared is 4.
Answer: y = 12.00 + (0.50)*(x - 2)
Step-by-step explanation:
x will be the game
y = cost
x - 2 because 2 is the initial
you can test it y = 12 + (0.50)*(3-2)
y = 12 +(0.50)*(1)
y = 12.50

the answer would be 16380
Hope this helped :)
Let the other 2 unknown sides be y n z
look at the two smaller triangles inside
y^2 = 12^2 + x^2 and
z^2 = 21^2 + x^2
from the biggest triangle
(12+21)^2 = y^2 + z^2
substituting
(12+21)^2 = (12^2 + x^2) + (21^2 + x^2)
33^2 = 12^2 + 21^2 + 2x^2
2x^2 = (33^2 - 12^2 - 21^2)/2 = 504
x^2 = 252
x = 15.9
ans is B
88= 10k when you cross-multiply so k= 8.8 when you divide 88 by 10
Hope this helps!
