Answer:
b. the base is 9 and the height is 6
Step-by-step explanation:
Answer:
600 cm^2
Step-by-step explanation:
The side length of one of the faces is 10 cm
The length of a side is generally noted as s.
In this problem s = 10
Area of a cube face = s^2
So the area of one face of a cube = s^2 = 10^2 = 10*10 = 100
There are 6 faces on a cube.
Area = 6 * 100 = 600
I believe that number would be 6.
1/3n-12= -10
+12 +12
_________
1/3n = +2
x3 x3
_________
n = 6
Answer:
= - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
= - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
