The volume of the pyramid is 
Explanation:
The height of the square pyramid is 18 cm
The base of the square pyramid is 11 cm
The volume of the square pyramid can be determined using the formula,
Substituting 
and 
in the formula, we have,
Simplifying, we have,
Multiplying, we get,
Dividing, we get,
Thus, the volume of the pyramid is
Answer:
k = 4
Step-by-step explanation:
The graph represents y and x in direct proportion with equation
y = kx ← k is the constant of proportionality
To find k use the point (1, 4), that is x = 1, y = 4
k = 
= 
= 4
They site there sources or give information to prove why there point is correct
Answer:
= 5 ( 12d + 23f )
Step-by-step explanation:
-2(5d-9f)+7f-10(-9f-7d
Open parenthesis
= -10d + 18f + 7f + 90f + 70d
Collect like terms
= -10d + 70d + 18f + 7f + 90f
= 60d + 115f
Factorise
= 5 ( 12d + 23f )
Therefore,
-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )
I think it is...
F(1)=1(2)-1+2 which equals -1
I'm not sure tho
