John claims the following two expressions are equivalent -2(5y 3) = 10y - 6
John's work in determining an expression equivalent to the first expression is shown below,
2(5y 3)
+(25)(-2% -3)
10y6
Which statement explains why John's olaim is incorrect?

A He should have subtracted (-2 * 3) resulting in the expression 107 * 6.

B He should have only multiplied 3 by 2 resulting in the expression by - 6

C He should have only multiplied Sy by 2 resulting in the expression - 1043

D He should have only multiplied 3 by 2 and subtracted (23) resulting in the expression Sy + 6

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
