Distributive property is
a(b+c)=ab+ac
we can make it easier by splitting up 63 into 60+3
so
7(63)=7(60+3)=7*60+7*3=420+21=441

Answer:
D. diagonal = 20.10 cm
Step-by-step explanation:
Find the bottom diagonal using the length and width.
diagonal² = 8² + 12²
diagonal = √64+144
diagonal = √208
diagonal = 4√13
---------------------------------------------------------------------------------------------------------
Find diagonal of the rectangular solid:
diagonal² = (4√13)² + 14²
diagonal² = 208 + 196
diagonal = √404
diagonal = 20.10 cm
