Savannah AndersonTo simplify ( 18(1 + 4a) - 3(20a - 20) ), follow these steps:
-
Distribute the terms inside the parentheses: ( 18 \times 1 + 18 \times 4a - 3 \times 20a + 3 \times 20 ).
-
Perform the multiplications: ( 18 + 72a - 60a + 60 ).
-
Combine like terms: ( 18 - 60 + 72a - 60a ).
-
Combine the constants: ( -42 + 12a ).
Therefore, ( 18(1 + 4a) - 3(20a - 20) ) simplifies to ( -42 + 12a ).
