Answer:
the expressions are not equivalent
Step-by-step explanation:
7(x+2y) (distribute 7 into the parentheses)
= x(7) + 2y(7)
= (7x + 14y) ≠ (14x + 14y)
hence the expressions are not equivalent
The cosine of 1.137020412 degrees is 0.4204.
(4a + 6b) x (2a - 2b)
the answer would be 8a2 + 4ab - 12b2
