Answer:

A: x^2+3x-4

B: 6x^2 -5x +1

Step-by-step explanation:

Alright, so for this, use the FOIL method, by multiplying the terms of each question in this order:

First

Outer

Inner

Last

So with the first question, lets do this:

(x+4)(x-1)

F: x * x = x^2

O: x * -1 = -x

I: x * 4 = 4x

L: 4 * -1 = -4

Then combine the like terms together:

x^2 + -x + 4x -4

A: x^2+3x-4

With the next one, same deal:

(2x-1)(3x-1)

F: 2x * 3x = 6x^2

O: 2x * -1 = -2x

I: 3x * -1 = -3x

L: -1 * -1 = 1

Then combine them up:

6x^2 -2x -3x +1

B: 6x^2 -5x +1

All done!

the product of two numbers is 7904, and the absolute value of one of the numbers is 247. Find two possible solutions for the oth
Nina [5.8K]

Two Possible solutions for the other number are -32 and 32.

<h3>What are absolute value of a number?</h3>

Absolute value describes the distance from zero that a number is on the number line, without considering direction.

Overall, To find the absolute value of a number :

Let we have any number n ( it can be positive/negative ).

so, Absolute value of 'n' will be | n | (mod of n) , means we have to take positive value of the given number.

For example: | -3 | = 3

| 4 | = 4

| -1000 | = 1000

Now, For absolute value -

For example: Absolute value of 29 is 29.

Absolute value of -56 is 56.

Absolute value of -1000 is 1000.

We have given the product of two numbers is 7904.

Let say we have number 'a' and 'b'.

so, here : a x b = 7904.        ------------ ( i )

The absolute value of one of the numbers is 247.

Let Absolute value of 'a' = 247

So the number 'a' can be either 247 or -247.

because absolute value of 247 is 247 and also absolute value of -247 is 247.

using equation ( i )

a x b = 7904

b = 7904 / a.

when a = 247

b =  32

when a = -247

b = - 32

Hence, Two Possible solutions for the other number are -32 and 32.

Explain how u can decide where to place the first digit of the answer for 6,139 / 153
storchak [24]

Answer:

The first digit would go in the tens place.

Step-by-step explanation:

First we estimate the approximate numbers. For 6130 we estimate 6000 and for 153 we estimate almost 150.

So dividing 6000 by 150 would give 40 .

The four would go in the ten's place .

Now check by dividing

         40.1     So the answer is correct. The quotient is 40.12.

153\sqrt{6139}

<u>       612</u>

           190

<u>            153</u>

<u>              37 </u>

The first digit would go in the tens place.

The answer is justified. We can easily decide where to place the first digit.
