Answer:
a) x^2 + y^2
b) 9-xy
Step-by-step explanation:
Here, we want to write the algebraic statements as expressions;
a) The sum of the squares of x and y
The square of x is x^2
The square of y is y^2
The sum of the squares is x^2 + y^2
ii) Product of x and y subtracted from 9
The product of x and y is x * y = xy
Subtracting these from 9, we have;
9-xy
Answer:
3n+12
Step-by-step explanation:
(n+4)3=
3n+12
Just multiply the number and variable inside the parentheses by 3
For this case we have:
By trigonometric property we have:
Where:
Substituting:
Clearing x we have:
Thus, the equation is:
Answer:
1 hour =60 minutes
So the answer is 0.1 mile/ minute
