8 0

Answer:

x = 3 \frac{1}{2}

Step-by-step explanation:

there's no x in the equation you wrote.

Did you mean?

2x + 8 = 15

Subtract 8 from both sides

2x = 7

Divide both sides by 2

x = 7/2

x = 3 \frac{1}{2}

The area of a rectangle is 10r (squared) − 11r − 6. The width is 2r − 3. What is the length?
sladkih [1.3K]
<span>10r^2 − 11r − 6 = (2r - 3)(5r +2)
so
A = </span>(2r - 3)(5r +2)<span>
as you know A =  L * W
if width = </span>(2r - 3) then length = (5r +2)

answer
length = (5r +2)

Maritza remembers her PIN because it is between 1,000 and 1,500 and it is the product of two consecutive prime numbers. What is
valentina_108 [34]

Answer:

<em>The PIN is 1147</em>

Step-by-step explanation:

<u>Prime numbers</u>

These are integer numbers that only divide exactly by themselves and by 1. To find the first possible prime number between 1,000 and 1,500, calculate the square root of 1,000.

\sqrt{1000}\approx 31.6

Thus, the first prime to consider is 31. Write the consecutive primes from 31:

31 , 37 , 41 , 43

We can see the only two consecutive primes whose product lies in the given interval are 31 and 37. Thus, the PIN is 31*37=1147

3) Prove that there is ann ∈ N such that 0.001 ∉ (0,1/n). (Hint: findsuch an n.)
Greeley [361]

Answer:

10000

Step-by-step explanation:

0.001 = 1/1000

so, we take an n bigger than 1000, let's say 10000, then 1/1000 > 1/10000 and 1/1000 ∉ (0, 1/10000).
