Please do number 12 for me.

Answer:

[tex] {x}^{4} - {x}^{3} - {9x}^{2} - {11x}^{2} - 4 [/tex]

Step-by-step explanation:

Since the roots are -1,-1,-1 and 4 we can that as.

[tex](x + 1)(x + 1)(x + 1)(x - 4)[/tex]

x+1=0, x equal -1, and x-4=0 and x equal 4. Then apply the foil method to one at a time and you equal the answer above.

Answer:

g = 1/3 x - 2/3

Step-by-step explanation:

x =3g + 2

Switch sides:

3g + 2 = x

Take away 2 from both sides:

3g = x - 2

Divide both sides by 3:

g = 1/3 x - 2/3

Answer:

Answer:

$80

Step-by-step explanation:

plug 40 into each equation for x

50+12(40)

simplify

50+480

simplify

530

10+15(40)

simplify

10+600

610

now subtract 530 from 610

610-530

Answer: 15

Step-by-step explanation:

From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:

= 63 × $5

= $315

We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:

= $315 / $20

= 15 3/4

Therefore, he will get 15 $20 bills

Answer: {-7, -6}

Explanation: When an equation has a squared term in it,

it's called a polynomial equation.

The rule for solving a polynomial equation

is to first set it equal to 0, then factor.

Since this equation is already set equal to 0, we can factor the left side.

The left side is a trinomial that can be

factored as the product of two binomials.

The first term in each binomial will be a factor of the w².

Since w² factors a w · w, we use a w as our first term.

For the last terms, we use factors of 42 that add

to 13 and these factors are +7 and +6.

So we have (w + 7)(w + 6) = 0.

So either w + 7 = 0 or w + 6 = 0.

Solving for w in each equation, we find that our solution set is {-7, -6}.

Answer:

2400000 in a hour

Answer:

By doing 3 divided by 5, you will get 3/5 of trail mix per person.

Step-by-step explanation:

The fraction of a bag of trail mix each friend gets will be 8/9.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Nine friends share 8 bags of trail mix equally.

Then the fraction of a bag of trail mix each friend gets will be given by the division of the number 8 by 9. Then the fraction is given as,

⇒ 8 / 9

The fraction of a bag of trail mix each friend gets will be 8/9.

Answer:

[tex]\frac{11}{6} y[/tex]  

Step-by-step explanation:

Since they all have y as the variable, you can simply add the coefficients (number in front of the variable) together. (y = 1y)

[tex]\frac{2}{3} + \frac{1}{6} + 1 = \frac{4}{6} + \frac{1}{6} + \frac{6}{6} = \frac{11}{6}[/tex] or [tex]1\frac{5}{6}[/tex]

Answer:

400000 pennies

Step-by-step explanation:

A penny is about 5×10^-3 feet thick. The One World Trade Center building is about 2,000 feet tall.

The number of pennies that would be in a stack of pennies as tall as the One World Trade Center building is calculated as:

Height of the building ÷ Thickness of a penny

Height of the building = 2000 feet

Thickness of a penny = 5 × 10^-3 feet

Hence:

= 2000feet/ 5 × 10^-3 feet

= 400000 pennies

Answer:

y=2x−5 is a line

Step-by-step explanation:

Explanation: y=2x−3 is in slope intercept form for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. The y-intercept is the point at which x=0 and y=−3 , which is point (0,−3) You can plot this point on your graph.
