Consider the trinomial 9x2 + 21x + 10. What value is placed on top of the X? What value is placed on the bottom of the X? What i

inna [77]

Answer: 1) Value is placed on top of the X =90

2) Value is placed on the bottom of the X =21

3) Factored form will be (3x+5)(3x+2)

Step-by-step explanation:

Since we have given that

$9x^2 + 21x + 10$

As we know the quadratic form :

$ax^2+bx+c=0$

1) Value is placed on top of the X is given by

$a\times c=9\times 10=90$

2) Value is placed on the bottom of the X is given by

$b=21$

3) Factorised form:

We will use "Split the middle term":

$9x^2 + 21x + 10\\\\=9x^2+15x+6x+10\\\\=3x(3x+5)+2(3x+5)\\\\=(3x+2)(3x+5)$

Hence, Factored form will be

(3x+5)(3x+2)

Which quantity is proportional to 90⁄2? Check all that are true. 45⁄1 15⁄3 180⁄3 180⁄4 270⁄8

Sati [7]

Answer:

45/1 and 180/4

Step-by-step explanation:

1. True

$\dfrac{90}{2}=\dfrac{45\cdot 2}{1\cdot 2}=\dfrac{45}{1}$

2. False

$\dfrac{15}{3}=\dfrac{3\cdot 5}{3\cdot 1}=\dfrac{5}{1}\neq \dfrac{45}{1}$

3. False

$\dfrac{180}{3}=\dfrac{60\cdot 3}{3\cdot 1}=\dfrac{60}{1}\neq \dfrac{45}{1}$

4. True

$\dfrac{180}{4}=\dfrac{45\cdot 4}{1\cdot 4}=\dfrac{45}{1}$

5. False

$\dfrac{270}{8}=\dfrac{135\cdot 2}{4\cdot 2}=\dfrac{135}{4}\neq \dfrac{45}{1}$
