Answer:
If the width is 5 cm and the length is 4 cm it satisfies both parts.
6 x 4 = 24
24 - 5 = 19
5 x 4 = area of 20
Step-by-step explanation:
So firstly, add both sides by 6: 
Next, multiply both sides by 4, and your answer will be 
Answer:
s = 40/10
Step-by-step explanation:
s = speed, d = distance, t = time
d = 40m, t = 10s
s = 40m/10s
Answer:
For this equation let's round the 3328 to a 3300.
Step-by-step explanation:
If we remove the 2 zeros, we remain with a 33. 33/6 is 5.5 Now if we add back 2 places we get 550. I know this is written badly, but I hope it helped.
Since f(x) is a polynomial with 3rd degree, then it will have 3 roots (zeroes)
One of them is real and the other two are complex conjugate roots
Since the real root is 4, then
x = 4
Since the complex root is (1 - i), then
The other root will be the conjugate of it (1 + i)
x = (1 - i)
x = (1 + i)
To find f(x) we will multiply the three factors of it
We can get the factors from the zeroes

Subtract 4 from both sides

The first factor is (x - 4)

The second factor is (x - 1 + i)
The third factor is (x - 1 - i)

We will multiply them to find f(x)

Multiply it by (x - 4)

The answer is
