Answer:

Step-by-step explanation:

If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.

x + 1 + 6x + 6 + 8

7x + 15 is your final answer.

However, I think the question is

(x + 1)^2 + 6(x + 1) + 8

Let y = x + 1

y^2 + 6y + 8

(y + 2)(y + 4)

(x + 1 + 2 ) ( x + 1 + 4)

(x + 3)(x + 5)

Answer:

172.5

Step-by-step explanation:

The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place

Answer:

3a^3

Step-by-step explanation:

Ok I got you bud now the the first thing to notice that they're all the same variable. so the way I learned to look at is like this  

1a^2 x 3a^1

so the reason I put it like this is so I remember that in front of every variable is a coefficient. so you would first multiply the coefficient

3x1=3

3

then multiply the a's you have one a that is being squared and one a to the first power so since your multiplying them you just add the exponents

a^1 + a^2 = a^3

so when you put it all together it says 3a^3

hope this helps

Answer:

the y-intercept is 8 and the slope is -4/3 .

Step-by-step explanation:

The y - intercept is (0, 8) and the slope is -4/3

"It is the point at which the graph of the function intersects the y-axis"

The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

For given example,

We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)

Using the slope formula,

⇒ slope = (0 - 8)/(6 - 0)

⇒ slope = (-8)/6

⇒ slope = -4/3

Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)

So, the y - intercept is (0, 8)

Therefore, the y - intercept is (0, 8) and the slope is -4/3

Answer:

11x + 8 +8x +12 =27  (drop the parenthesis, there's no actual need for them)

19x +20 =27 (i combined like terms and then subtracted 20 from both sides)

19x = 7  (divide both sides by 19 to get x alone)

x= 7/19 or 0.36842105 (the answer)

Answer:

  38.5°

Step-by-step explanation:

A triangle solver can give an answer easily. The angle is 38.5°.

__

The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.

  C = arccos((a² +b² -c²)/(2ab))

Here, we have a=35, b=48, c=30, so the angle is ...

  C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°

The angle the cable makes with the pole is about 38.5°.

The answer is below

Step-by-step explanation:

Hana has some blue paint. She wants to lighten the shade, so she mixes in 1  cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of  white paint at a time. After adding 4 cups, she decides the color is too light.

How would she express the amount of paint to add to be between too dark and too light.

Solution:

After adding a cup of white paint, the color is still dark, she adds the second cup of paint and the color is still dark. She adds the third cup of paint and the color is still dark but when she adds the fourth cup of white paint, the color became too light.

This means that the amount of paint to add to be between too dark and too light is between the third and fourth cup.

Let w represent the amount of paint to add to be between too dark and too light. Hence:

3 < w < 4
