What is the result when 9r^3 + 27x^2 + 11x +1 is divided by 3x + 1?​
morpeh [17]

Answer:

the answer is 3x^2 + 8x + 1

Step-by-step explanation:

(I used x as the variable due to the invalid difference of variables in your question )

To find the correct answer, I had to use polynomial division.

(9 x 3 + 27 x 2 + 11 x + 1) / (3 x + 1)

= ( 3 x + 1 ) ( 3 x 2 + 8 x + 1 ) / (3 x + 1)

= 3 x 2 + 8 x + 1

Answer:

THE CORRECT OPTION IS C) Δ RST \sim Δ UVW ; \frac{5}{6}

Step-by-step explanation:

i) ∠ WUV = ∠ TRS      ( same angle = 32 )

ii) \frac{TR}{UW}  = \frac{RS}{VU}  = \frac{15}{18} = \frac{10}{12} = \frac{5}{6} ;

Hence it is proved that

Δ RST \sim Δ UVW

3.5 + 1.2(6.3 – 7x) = 9.38
Vladimir [108]

Answer: 0.2

Step-by-step explanation:

subtract 9.38 - 3.5 = 5.88

distribute the 1.2.

7.56 - 8.4x = 5.88

subtract 5.88 - 7.56 = -1.68

-8.4x = -1.68

divide both sides by -8.4

answer = 0.2
