This
Answer:
9
Step-by-step explanation:
Given,
Side of square = 3 feet.
To find : Area of square = ?
Formula : -
Area of square = ( side )²
Area of square
= 3²
= 3 x 3
= 9 feet²
Therefore,
The unit of it's area will be 9 feet².
Answer:
x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
Answer:
x=12
Step-by-step explanation:
We know that a right angle is 90 degrees. So we can make the equation 
Now, we can solve fore X! We can combine 35 and 7 to make the equation 
. In order to isolate x we have to subtract 42 from both sides, getting us the equation 
Now, in order to isolate x we must divide each side by 4, getting us the equation 
. To prove that x=12, we can subsitute x for 12. This means that we can do 
which simplified, is 90=90, making x=12 true. Hope this helps :)
Answer:
-13
Step-by-step explanation:
3x^3 - 2y^-6x^2y^2+xy
x=2/3 and y=1/2
Solve :
3x^3 - 2y^-6x^2y^2+xy
Put value of x and y in this equation
= 3(2/3)^3 - 2(1/2)^-6(2/3)^2(1/2)^2+(2/3)(1/2)
= -13
