All you have to do, is combine like terms. Let's go through it:

Arrange it so you can easily combine like terms:

So, your answer for the sum is 1) 7x² - 10x + 2
Answer:
<h3>n>-5/2</h3>
Step-by-step explanation:
First, you have to isolate it on one side of the equation. Remember that, isolate n on one side of the equation.
6n-3>-18
6n-3+3>-18+3 (Add 3 from both sides.)
-18+3 (Solve.)
-18+3=-15
6n>-15
6n/6>-15/6 (Divide by 6 from both sides.)
-15/6 (Solve.)
-15/6=-5/2
n>-5/2
In conclusion, the correct answer is n>-5/2.
<span>One cup of water weighs approximately 8 ounces, which is equal to 225 grams. One cup holds 225 milliliters of water. The volume and weight of 1 cup of water are the same number under the metric system because the density of water is 1 gram per milliliter.</span>
Answer:
LCM (8,10) = 2 × 2 × 2 × 5 = 40
Step-by-step explanation:
Least common multiple is the smallest number that is multiple of both the given numbers.
Example: LCM of 2 and 3 is 6 .
6 is a multiple of both 2 and 3 .
Given numbers are 8 and 10
First write both in factor form,
⇒ 8 = 2 × 2 × 2
⇒ 10 = 2 × 5
We find LCM by writing common terms one times and multiplying all terms together,
Here, 2 is common to both 8 and 10 so we write it once only.
Thus, LCM (8,10) = 2 × 2 × 2 × 5 = 40.
