The size of a certain cell is 2.5*10^-9m. another cell is 1.5*10^3 times larger. how large is the larger cell in scientific notation?

Will mark brainliest. need asap. what is the equation of the line that goes through ( - 1, - 4) and parallel to the line 3x + y = 5.

Mika taught her sister the steps for dividing a decimal by a decimal. which instructions are correct? 1. multiply the divisor by a multiple of 10 to create an integer divisor. 2. multiply the dividend by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. multiply the dividend by a multiple of 10 to create an integer. 2. multiply the divisor by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. divide the divisor by a multiple of 10 to create an integer divisor. 2. divide the dividend by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. divide the dividend by a multiple of 10 to create an integer. 2. divide the divisor by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers.huy
