Answers

Answer 1

Answer:

Answer:

x² + 5x + 4

Step-by-step explanation:

(x + 1) (x + 4)

apply the FOIL method

xx + (x * 4) + (1 * x) + (1 * 4)

xx + 4x + (1 * x) + (1 * 4)

xx + 4x + 1x + 4

x² + 5x + 4

Answer 2

Answer: x(x+1) 1(x+4)
x^2+x+x+4

I can't help you, but I can provide an example related to this question.

In the 2009-2010 school year in country A, there were 116,000 foreign students from country B.In the 2009-2010 school year in country A, there were 116,000 foreign students from country B. This number is 22% more than the number of students from country C. How many foreign students were from country C?

If x represents the number of students from country C.

then 122% of x = 116,000

122/100 * x = 116000

Transposing the formula for x;

therefore x = 116000 * 100/122 = 95,082 students

What are the factors of 6tu

Answers

Depending on the value of 't' and 'u', the numerical value of that expression
could have almost anything for factors.

For example, if 't' happens to be 3 and 'u' happens to be 10, then 6tu = 180,
and the factors of 6tu are

1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180.

But that would only be temporary ... only as long as t=3 and u=10.

The only factors you can always count on, that don't depend on the values
of 't' and 'u', are

1, 6, t, u, 6t, 6u, tu, and 6tu .

0.7(3s+4)−1.1s=7.9 I need a answer

Answers

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)

Answer:

$\boxed {s = 5.1}$

Step-by-step explanation:

Solve for the value of $s$ :

$0.7(3s + 4) - 1.1s = 7.9$

-Use Distributive Property:

$0.7(3s + 4) - 1.1s = 7.9$

$2.1s + 2.8 - 1.1s = 7.9$

-Combine like terms:

$2.1s + 2.8 - 1.1s = 7.9$

$s + 2.8 = 7.9$

-Subtract $2.8$ to both sides:

$s + 2.8 - 2.8 = 7.9 - 2.8$

$\boxed {s = 5.1}$

So, the value of $x$ is $5.1$ .

Solve this question? 7x - 3x +7 =3 (x - 4)+20

Answers

x=1

To solve this you start by adding like terms on the left side and doing the distributive property and adding like terms on the right. This would get you
4x+7=3x+8

Then you minus 3x on both sides getting
x+7=8

Then subtract 7 from both sides getting x=1.

7x - 3x + 7 = 3 ( x - 4 ) +20
⇔ 4x + 7 = 3x - 12 + 20
⇔ 4x - 3x = 8 - 7
⇔ x = 1
