Explain how the expression 5 x (6-4) and 5 x 6-4 are different

Because of PEMDAS you would answer 6-4 first in the equation 5x(6-4) because it is in parentheses. Since there are no parentheses in 5x6-4 you would multiply 5x6 first.

The expressions 5 x (6 - 4) and 5 x 6 - 4 are different because....

Anything inside the parentheses has to be done first so 5 x (6 - 4) the 6 -4 has to be done first but in 5 x 6 - 4 you have to follow PEMDAS and do multiplication first.

Hope I helped!

Which of the following represents a geometric series (remember what a series is as opposed to a sequence)?

juin [17]

Answer:

4 + 12 + 36 + ...

Step-by-step explanation:

4, 12, 36, ... is a geometric sequence, it has a common ratio of $r=\frac{36}{12}=\frac{12}{4}=3$

When we add the terms of a geometric sequence we get a geometric series.

4+12+36+ ... is a geometric series, it has a common ratio of $r=\frac{36}{12}=\frac{12}{4}=3$

4 + 12 + 20 + ... is not a geometric series because it has no common ratio

$\frac{20}{12}\ne \frac{12}{4}$

The second choice is correct

1. round the result to 2 decimal places. -0.9x+2.8=4.1

lora16 [44]

1. -0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
c) -1.44

A tomato plant grew an average of 0.06 m per day. How many days did it take for the plant to grow a total of 0.96 m.

If you divide 96 by 6 then you get 16. So it's 16 days!
