Rewrite the equation by completing the square. 4 x^{2} +20x +25 =0

Ede4ka [16]

Answer:

(x+5/2)^2 = 0

Step-by-step explanation:

4 x^{2} +20x +25 =0

Divide by 4

4/4 x^{2} +20/4x +25/4 =0

x^2 +5x +25/4 =0

Subtract 25/4 from each side

x^2 +5x +25/4 -25/4 =-25/4

x^2 +5x =-25/4

Take the coefficent of x

Divide by 2

5/2

Square it

25/4

Add it to each side

x^2 +5x +25/4 =-25/4+25/4

(x+5/2)^2 = 0

Take the square root of each side

x+5/2 = 0

x = -5/2

0.4 divided by 0.08 show your work

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Since we have not instructed to follow any kind of rule dividing, we can write in any form. Let's calculate it using fraction

$0.4:0.08=\frac{0.4}{0.08}$

We can multiply both the nominator and denominator with 100

$\frac{0.4}{0.08}=\frac{40}{8}=5$

The answer is 5.

We can also solve it as a division of fractions:

$\frac{4}{10} : \frac{8}{100} = \frac{4}{10} * \frac{100}{8} = \frac{10}{2} = 5$
