When multiplying decimals, what you do with the decimal point is; C: line up the decimal points
<h3>How to Multiply Decimals?</h3>
A common way to multiply decimals is to treat them as whole numbers, and then position the decimal point in the product. The number of digits after the decimal points in the factors determines where the decimal point is placed in the answer. For example, 0.3 x 0.8 = 0.24.
Now, when multiplying decimals, the most important step is to line up the decimal points. Line up the decimal points so that similar place values are lined up. In other words, the tens place in both numbers should be lined up, the ones place in both numbers should be lined up as well and son.
Thus, option C is the correct answer.

Answer:
Although the Line is included in the region, I will say the your answer is B and D
Step-by-step explanation:
The region shaded is below the Line graph, son we have a < sign, now, I can see the region including the Line graph, so I will say that the inequality should have the = sign, nevertheless no options include the =sign, so, if it is nothing missing, your answer should be:
y<x
Answer:
a) 6r + 3
b) 8 + 4d
c) -2mn
d) 6s - 10
Step-by-step explanation:
a) 2r + 3 + 4r
We need to add the like terms
= 2r + 4r + 3
= 6r + 3
b) 8 + 3d + d
We need to add the like terms
= 8 + 3d + d
= 8+4d
c) mn + (–3mn)
We need to add the like terms
= mn - 3mn
= -2mn
d) 10s + (–10) + (–4s)
We need to add the like terms
= 10s –10 –4s
= 10s - 4s - 10
= 6s - 10
Answer:
C. (5x + 6) (5x - 6)
Step-by-step explanation:
25 is a perfect square, meaning its two factors are identical (5), and 36 is also a perfect square with two identical factors (6). With this information, we can split the expression below like this:
Since 36 is negative, we have to have a positive 6 and a negative 6:
(5x - 6) (5x + 6)
