Answer:
4x + 4y + 12
Step-by-step explanation:
x + 3y − y + 3x + 2(2 + 4 + y)
Apply Distributive Property:
2(2 + 4 + y)
2*2=4
2*4=8
2*y = 2y
x + 3y − y + 3x + 4 + 8 + 2y
Combine Like Terms:
x + 3x +2y +3y - y + 4 + 8
4x + 4y + 12
Answer:1/(8a^12)
Step-by-step explanation:
(2a^4)^-3
2^(-3) x (a^4)^(-3)
1/(2^3) x a^(-12)
1/(2x2x2) x 1/(a^12)
1/8 x 1/a^12
1/(8a^12)
Answer:
a, d and e.
Step-by-step explanation:
A perfect square is one where the coefficient is a perfect square and the exponent is even.
So they are 25x^12, 36x^16 and 9x^8.
Answer:
D
Step-by-step explanation:
Multiply by 3
4 x 3 = 12
9 x 3 = 27
X+x+1+x+2=51
3x+3=51
Use inverse operations to solve
subtract 3 from both sides
3x=48
Divide by 3 on both sides
x=16
