1.( 2x ) ( 10x ) = 20 x²
2. -3m( m + 8 ) = -3m² - 24m
3. 4d( 2d -9 ) = 8d² - 36d
4. ( 3x + 4 ) ( x -2 ) = 3x² - 6x + 4x - 8 = 3x² - 2x -8

5. ( 2y -1 ) ( 4y - 3 ) = 8y</span>² - 6y - 4y + 3 = 8y² -10y +3
Answer:
The question = (7^3)*(7^x)
When multiplying two exponents with the same base, all you do is add the exponents together and keep the same base
Therefore,
(7^3)*(7^x) = 7^(3+x)
Step-by-step explanation:
7^3+x is the answer
Answer:

Answer:
C) 12.2 cm
Step-by-step explanation:
