Step-by-step explanation:
Remember that

so

Decompose the numbers 18 and 42 in prime factors
we know that


Find the least common multiple (LCM)
The LCM is

we need to find all multiples of 126 that are less than or equal 900.

therefore
7 times during the first 15 minutes
They all show 50.029
The correct answers are:
A.) <span>5 × 10 + 0 × 1 + 0 × 1/10 + 2 ×1/100 + 9 × 1/1000
Sorry.
This is all I can find correct
Its a little hard when you post the tenths, hundredths, and thousandths as fractions, but A is all I can find.

Answer:
5
Step-by-step explanation:
(4v-3w)∧2, Its to the second power so take the exponent 2 and put it on the variables and coefficients so you would have (4∧2)(v∧2)-(3∧2)(w∧2). Then you would do the math and get 16v∧2-9w∧2 than you would add the like terms so you have 25v∧2w∧2.
