228 ft²
To find the area of any rectangular space, you multiply its length by its width. In this case, you multiply together 12 and 19 to get 228.
Answer:
3x³ + 2x² - x + 3
Step-by-step explanation:
AB = x²(3x + 2) = 3x³ + 2x²
AB - C = 3x³ + 2x² - (x - 3)
= 3x³ + 2x² - x + 3
= 3x³ + 2x² - x + 3 ← in standard form
Yes you are correct, GCF of both terms is x, so you can factor x out.
3x - x² ⇒ x(3 - x)
Answer:
[-2,7] is the solution of inequality .
Step-by-step explanation:
Given : inequality 2 | 5 - 2x | - 3 ≤ 15
To find: solution of inequality.
Solution : We have given that 2 | 5 - 2x | - 3 ≤ 15
.
On adding 3 both sides:
2 | 5 - 2x | - 3+3 ≤ 15
+3
2 | 5 - 2x | ≤ 18.
ON dividing both side by 2 and simplify
| 5 - 2x | ≤ 9.
On applying absolute rule, if | u | ≤ a,a> then -a ≤ u≤ a
-9≤5 - 2x ≤ 9.
5 - 2x ≤ 9 , 5 - 2x ≤ -9.
- 2x ≤ 9-5
- 2x ≤ 4
On dividing by -2
x ≥ -2.
For 5 - 2x ≤ -9.
- 2x ≤ -9-5
- 2x ≤ -14
On dividing by -2
x ≤ 7
Therefore , [-2,7] is the solution of inequality .
