So for this, I will be factoring by grouping. Firstly, what two terms have a product of 20x² and a sum of 12x? That would be 2x and 10x. Replace 12x with 2x + 10x:

$4x^2+2x+10x+5$

Next, factor 4x² + 2x and 10x + 5 separately. Make sure that they have the same quantity inside the parentheses:

$2x(2x+1)+5(2x+1)$

<u>Now you can rewrite the expression as $(2x+5)(2x+1)$ , which is your final answer.</u>

if you meant that then, you would do this. turn it into 4x^2+10x+2x+4. the factor out the 2x which would be 2x(2x+5)+2x+5 and then factor the 2x+5 which would become (2x+5)x(2x+1)

Answer:

The original price range of soda is $10 to $39.4

Step-by-step explanation:

Given as :

The discount coupon applied on grocery = 5%

The cost of soda after discount coupon ranges = $0.50 to $1.97

Let the original price range of soda = $A

Now, According to question

discount on original price = the cost after discount

So, initial original price = x

5% of x = $0.50

0.05 × x = $0.50

∴ x = $\dfrac{0.50}{0.05}$

i.e x = $10

Again final original price = y

5% of y = $1.97

0.05 × y = $1.97

∴ y = $\dfrac{1.97}{0.05}$

i.e y = $39.4

So, The original price range of soda = $A = $10 to $39.4

Hence, The original price range of soda is $10 to $39.4 Answer

Write the following quotient in the form a+bi.<br> -7i/2-7i

Helga [31]

Answer:

$\large\boxed{\dfrac{49}{53}-\dfrac{14}{53}i}$

Step-by-step explanation:

$\text{Use}\\\\i=\sqrt{-1}\to i^2=-1\\\\(a-b)(a+b)=a^2-b^2\to(a-bi)(a+bi)=a^2+b^2\\\\\text{distributive property}\ a(b+c)=ab+ac\\---------------------\\\\\dfrac{-7i}{2-7i}=\dfrac{-7i}{2-7i}\cdot\dfrac{2+7i}{2+7i}=\dfrac{-7i(2+7i)}{2^2+7^2}=\dfrac{(-7i)(2)+(-7i)(7i)}{4+49}\\\\=\dfrac{-14i-49i^2}{53}=\dfrac{-14i-49(-1)}{53}=\dfrac{-14i+49}{53}\\\\=\dfrac{49}{53}-\dfrac{14}{53}i$
