using the remainder theorem which quotient has a remainder of 20?
Answers
Answer:
D
Step-by-step explanation:
When a polynomial f(x) is divided by (x - a) then remainder is f(a)
A
divided by (x + 4 ), then a = - 4
[tex](-4)^{4}[/tex] - 8(- 4)² + 16 = 256 - 128 + 16 = 144 ≠ 20
B
divided by (x - 2), then a = 2
3(2)³ + 7(2)² + 5(2) + 2
= 3(8) + 7(4) + 10 + 2
= 24 + 28 + 12 = = 64 ≠ 20
C
divided by (x + 5) , then a = - 5
(- 5)³ + 5(- 5)² - 4(- 5) + 6
= - 125 + 125 + 20 + 6 = 26 ≠ 20
D
divided by (x - 2), then a = 2
3[tex](2)^{4}[/tex] - 5(2)³ + 5(2) + 2
= 3(16) - 5(8) + 10 + 2

Answers
Answer:
9 sqrt(5)
Step-by-step explanation:
La altura relativa a la hipotenusa corta la hipotenusa en dos segmentos.
Defina x como
x = la longitud de uno de esos segmentos
Entonces, la longitud del otro segmento = 15 - x.
Entonces, por el teorema, tenemos que (15-x) (x) = 36, de modo que
15x - x ^ 2 = 36
x ^ 2 - 15x + 36 = 0
(x-3) (x-12) = 0
Entonces, x = 3 o x = 12.
Sin pérdida de generalidad. sea x = 3.
Entonces, la suma de las dos piernas es
raíz cuadrada (6 ^ 2 + 3 ^ 2) + raíz cuadrada (12 ^ 2 + 6 ^ 2) =

What is the product?
Answers
Answer:
300/1 or 300
Step-by-step explanation:
I took the quiz
The product of the given numbers is 29,89,854.
The given expression is [(−427⋅(−18))⋅((−389)⋅(−1))].
What is product of integers?Integers are the set of whole numbers and their opposites. When you multiply integers, the numbers that you are multiplying are called factors. Your answer after multiplying is called a product.
Product of negative and negative integers is positive.
Now,
(−427⋅(−18)) = 7686
((−389)⋅(−1)) = 389
7686 × 389 = 29,89,854
Therefore, the product of the given numbers is 29,89,854.
