Suppose that $a$ is a positive integer for which the least common multiple of $a+1$ and $a-5$ is $10508$. What is $a^2 - 4a + 1$
Nana76 [90]

Answer:

21022.

Step-by-step explanation:

Find the prime factors of 10508:

2 ) 10508

2 ) 5254

37 ) 2627

       71.

50208 = 2*2*37*71.

Now there is no integer value for a that would fit  (a+ 1)(a - 5) = 10508 .

But we could try multiplying the LCM by 2:-

= 21016  = 2*2*2*37*71.

= 2*2*37 multiplied by 2 * 71

= 148 * 142.

That looks promising!!

a - 5 = 142 and

a + 1 = 148

This gives  2a - 4 = 290

2a = 294

a = 147.

So substituting a = 147 into a^2 - 4a + 1 we get:

= 21022.

How are the commutative property of addition and multiplication alike?
Natasha_Volkova [10]

Answer:

Simply put, the <u>commutative property of multiplication means that no matter how you order the numbers you are multiplying, you will get the same answer</u>. Addition also <em>shares the commutative property with multiplication, whereas division and subtraction do not</em>.

Explanation:

In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it. Most familiar as the name of the property that says "3 + 4 = 4 + 3" or "2 × 5 = 5 × 2", the property can also be used in more advanced settings.

The price of a carton of eggs at Supermarket A is $2.10. The price of a carton of eggs at Supermarket B is 40% less than the pri
igor_vitrenko [27]

Answer:

84 Percentage increase

Step-by-step explanation:

Detailed calculations & verification

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

40% = 40/100 = 40 ÷ 100 = 0.4.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 40% of its value.

Percentage increase = 40% × 210

New value = 210 + Percentage increase

Calculate the New Value

New value =

210 + Percentage increase =

210 + (40% × 210) =

210 + 40% × 210 =

(1 + 40%) × 210 =

(100% + 40%) × 210 =

140% × 210 =

140 ÷ 100 × 210 =

140 × 210 ÷ 100 =

29,400 ÷ 100 =

294

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 210 =

294 - 210 =

How many solutions a system of linear equations have if: Questions. 1.the equations have different slopes? 2.the equations have
KATRIN_1 [288]

Answer:

see below

Step-by-step explanation:

1.the equations have different slopes?  They will intersect at one point so one solution

2.the equations have the same slope and different y-intercepts.  They are parallel lines with a different y intercept so they will never intersect - no solutions

3.the equations have the same slope and same y-intercepts. they are the same line so they have infinite solutions
