Answer:
a^2 + b^2 + 2ab - (3xy)^1/3
Step-by-step explanation:
Here we want to make a subtraction
Cube root of the product of x and 3y
x * 3y = 3xy
Cube root of this;
(3xy)^1/3
The sum of a and b is (a + b)
Square of this sum;
(a + b)^2 = a^2 + 2ab + b^2
Now, subtract the cube root
we have;
a^2 + b^2 + 2ab - (3xy)^1/3
Answer:
the answer is c.840
Step-by-step explanation:
you multiply 15 4 times and multiply it with 14 that would give us 840
Answer:750
Step-by-step explanation:
because you need to find the area of 1 tile then multiply it by 100
Answer:
C
Step-by-step explanation:
The area (A) of a regular decagon is
A = 
perimeter × apothem
perimeter = 10 × 8 = 80 in, thus
A = 0.5 × 80 × 12.3 = 492 in² → D
