Answer:

The number is 135.

Step-by-step explanation:

<u>1) Form an equation</u>

Three is subtracted from a number

⇒ x-3 (where x is "the number")

The difference is divided by 11

⇒ \displaystyle \frac{x-3}{11}

The result is 12

⇒ \displaystyle \frac{x-3}{11}=12

<u>2) Solve the equation</u>

\displaystyle \frac{x-3}{11}=12

Multiply both sides by 11

\displaystyle \frac{x-3}{11}*11=12*11\\\\x-3=132

Add 3 to both sides

x-3+3=132+3\\x=135

Therefore, the number is 135.

I hope this helps!

Answer:

<u><em>Question 1:</em></u>

The smallest 5-digit no. is <u><em>10,000</em></u>

<u>The product of its prime factors is:</u>

=> 10,000 = 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5

<u><em>Question 2:</em></u>

The prime factors of 1729 are:

=> 1729 = 7 × 13 × 19

The relation between their 2 consecutive prime factor is that when they both are subtracted, they give the result 6

<u><em>Such as :</em></u>

=> 13-7 = 6

=> 19-13 = 6

Hope this helps!

( 3 x 2 ) ^ 4 x 3 ^ -3 / 2 ^ 3 x 3 =<br><br> Simplify the exponential expression
Korvikt [17]

Answer:

2

Step-by-step explanation:

\frac{(3*2)^4*3^{-3}}{2^3*3}

we start simplifying by removing the parenthesis

Multiply the exponents inside the the parenthesis

3^4  * 2^4

\frac{3^4*2^4*3^{-3}}{2^3*3}

Now we apply exponential property

a^m * a^n = a^ (m+n)

3^4 * 3^-3 = 3^ (4-3) = 3^1

3 or 3^1  are same

\frac{3^1*2^4}{2^3*3^1}

3^1 at the top and bottom so we cancel it out

\frac{2^4}{2^3}

we apply log property . a^m / a^n = a^m-n

Now subtract the exponents

2^(4-3) = 2^1 = 2

HELP ASAP!!! Identify the factored form of each polynomial
Elenna [48]

Answer:

9x2 +42x + 24 <u>is</u> (x + 4) (9x + 6)

9x2 + 30x + 24 <u>is</u> (3x + 6) (3x + 4)

9x2 + 58x + 24 <u>is</u> (9x + 4) (3x + 4)

I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)
