The zeros of this function is -4 and -8
viktelen [127]3 years ago
3 0

Answer:

Step-by-step explanation:

The given equation is:

f(x)=x^2+12x+32

Simplifying the above expression, we have

f(x)=x^2+4x+8x+32

f(x)=x(x+4)+8(x+4)

f(x)=(x+4)(x+8)

Thus, zeroes of the given function will be:

f(x)=0

(x+4)(x+8)=0

x=-4 and x=-8

Therefore the zeroes of the given function are x=-4 and x=-8.

12 is 90% of what number?<br><br><br> with steps
a_sh-v [17]

Answer:

<h3><u>Let's</u><u> </u><u>understand the concept</u><u>:</u><u>-</u></h3>
  • Here 12 is 90% of a number.
  • So we can say that 90% of That number is 12 .
  • In this way we can get the the number
<h3><u>Solution</u><u>:</u><u>-</u></h3>

Let,

the number=x

<h3>According to the question ,</h3>

{:}\longrightarrow\sf 90\% \:of \;x=12

  • We know 90%=90/100
  • so add it

{:}\longrightarrow\sf {\dfrac {90}{100}}\times x=12

{:}\longrightarrow\sf {\dfrac {90x}{100}}=12

  • Now use cross multiplication method

{:}\longrightarrow\sf 90x=12\times 100

{:}\longrightarrow\sf 90x=1200

  • Now interchange sides .

{:}\longrightarrow\sf x={\dfrac {1200}{90}}

{:}\longrightarrow\sf x={\dfrac {200}{15}}

  • Answer will come in decimals so we take approximate value.

{:}\longrightarrow\sf x=13.3

{:}\longrightarrow\sf x=approximately \:13

\thereforeThe number is 13.
