9 sq. units refers to a 2d figure
9 cubed units refers to a 3d figure
so
9*9 would be sq. unit cuz dimensions of square
9*9*9 would be cubed unit cuz dimensions of cube
so in simple, 9^2,
and 9^3
the answer would be 8.
2 times 8 = 16 minus 5 = 11
A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.
The total cost = original cost + VAT
Total Cost = 927 + 20% * 927
20% converts to decimal by moving the decimal 2 units up, so it is 0.2
= 927 + 0.2*927
Multiply to find value of tax
= 927 + 185.4
Add to find the total cost
Total cost = 1112.4 euros
Answer:
I understand how to solve quadratice equations, but what do you do if it is equal to f(x). I am guessing that you set if equal to 0, but could anyone confirm?
f(x) = x^2 -6x +13. As an example. Have a great day
Step-by-step explanation:
Answer:
X+2y+x+2
=2x+2y+2
=2(x+y+1
Step-by-step explanation:
The expression is similar to 2(x+y+1)
