Answer:
x⁴ + x³ + 4x² - 5x
Step-by-step explanation:
The polynomials given in the question are:
x⁴ - 3x + 1
4x² - 2x + 8
x³ - 9
We have to add all them
First write all the polynomial in the summation form:
(x⁴ - 3x + 1) + (4x² - 2x + 8) + (x³ - 9)
Open the brackets:
x⁴ - 3x + 1 + 4x² - 2x + 8 + x³ - 9
Group together the similar terms
(x⁴) + (x³) + (4x²) + (-3x -2x) + (1 + 8 - 9)
Finding the sum in brackets:
x⁴ + x³ + 4x² + (-5x) + (0)
x⁴ + x³ + 4x² - 5x
Note that the sum is in descending powers of x
Answer:
<u>A = 2 , B = 10 and C = 18</u>
Step-by-step explanation:
Let the the missing numbers in the boxes are: A , B and C.
Given:
Time : Distance
A : 3
6 : 9
B : 15
12 : C
From the second raw, we can deduce that:
When the time = 6, the distance = 9
We will use the ratio and proportional to find A , B and C
So,
A/6 = 3/9 ⇒ A = 6 * 3/9 = 2
6/B = 9/15 ⇒ B = 6*15/9 = 10
6/12 = 9/C ⇒ C = 9*12/6 = 18
<u>So, A = 2 , B = 10 and C = 18</u>
