Answer:

[tex]90y^4-120y-360y^3+30y^2 = 30y((y - 4)(3y^2+1))[/tex]

Step-by-step explanation:

Given

[tex]90y^4-120y-360y^3+30y^2[/tex]

Required

Simplify

[tex]90y^4-120y-360y^3+30y^2[/tex]

Factor out 30y

[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^3 - 4 - 12y^2 + y)[/tex]

Reorder the expression

[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^3 - 12y^2 +y - 4 )[/tex]

Factorize

[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^2(y - 4) +(y - 4) )[/tex]

Combine the factors

[tex]90y^4-120y-360y^3+30y^2 = 30y((3y^2+1)(y - 4))[/tex]

Rewrite as:

[tex]90y^4-120y-360y^3+30y^2 = 30y((y - 4)(3y^2+1))[/tex]

Answer:

Around 300 Miles

Step-by-step explanation:

Nots sure of the exact number. If 28% of the trip is 101 miles then 50% would be around 210 miles.

So the entire trip as a whole should be near 300 miles.

Answer:

  40°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  (6x)° +x° +(2x)° = 180°

Answer:

145

Step-by-step explanation:

Each triangular side is 30ft

bottom is a 5*5 so it 25ft

30*4(#of sides)=120

120+25(bottom)=145

Answer:

I will give you the easy explanation here, go down there though to get a more complexed explanation and answer. Seeing it is a triangle, you can not multiply the 12 by 5. You have to multiply it by 2.5 because it dips in (because it's a triangle). Now you multiply the 5x5 to get 25. Now we have 25 for the base and 30 for each side. 30x4 to represent each side and add 25 for the base to get 145 as the final answer.

Step-by-step explanation:

Ok, they made this really easy with the 5's. You multiply the 5 by the 5 to get 25 in which the 12 there is about half of that, that made things really easy. Since the 12 goes to the middle that means that we can take what is from the middle to the side removing the half there getting you -2. Therefore, 12-2=10. Meaning the center is 10.

Answer: 2 pizzas

Step-by-step explanation:

Answer:

3 whole pizzas:

2 pepperoni

1 cheese

Step-by-step explanation:

What we know:

Pepperoni: Abe and Becca

Cheese: Cam and Kim

Solve:

Abe wants 1/2 a pizza and Becca want [tex]\frac{2}{3}[/tex]'s of a pizza

I gave both fractions a common denominator of 6

New Fractions: Abe- 3/6 Becca- 4/6

I then added them together and got 1 1/6

I did the same thing with Cam and Kim (but with the denominator of 12)

New Fractions: Cam-6/12 Kim- 4/12

I then added them together and got 10/12

So, Abe and Becca needed 2 pizzas, and Cam and Kim needed 1/

Answer:

2.5

Step-by-step explanation:

Answer:

0.15% of the students spent more than 557 on textbooks in a semester

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 473

Standard deviation = 28

According to the standard deviation rule, almost 0.15% of the students spent more than what amount of money on textbooks in a semester?

99.7% of the measures are within 3 standard deviations of the mean, so 100 - 99.7% = 0.3% are more than 3 standard deviations from the mean.

The normal distribution is symmetric, which means that 0.3%/2 = 0.15% spend less than 3 standard deviations below the mean, and 0.15% spend more than 3 standard deviations above the mean.

473 + 3*28 = 473 + 84 = 557

0.15% of the students spent more than 557 on textbooks in a semester

Answer:

25

Step-by-step explanation:

i think you mean +10x

but (x+a)^2 = x^2 + 2ax + a^2

2ax = 10x

ax = 5x

a = 5

so (x+5)^2 = x^2+10x+25

Answer:

[tex]y=-7x-2[/tex]

Step-by-step explanation:

We can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

Let (-1, 5) be (x₁, y₁) and our slope m is -7. By substitution:

[tex]y-(5)=-7(x-(-1))[/tex]

Distribute:

[tex]y-5=- 7 x - 7[/tex]

Adding 5 to both sides gives us our equation:

[tex]y=-7x-2[/tex]
