evaluate the Expression when n= -4

[tex] {n}^{2} + 6n + 9[/tex]
​

Answer:

Zeros are at x=0 and x=3/2.

Step-by-step explanation:

f(x) = x(6x - 9)

x=0 and 6x -9 = 0

6x = 9

x = 3/2

Given :

The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C.

To Find :

The final temperature on Sunday.

Solution :

Temperature on Saturday = initial temperature + 4⁰C

= 32⁰C + 4⁰C

= 36⁰C.

Temperature on Sunday = temperature on Saturday - 7⁰C

= 36⁰C - 7⁰C

= 29⁰C

Therefore, final temperature on Sunday is 29⁰C.

Hence, this is the required solution.

Answer:

DE = 15, AB = 6

Step-by-step explanation:

Because the triangles are similar, that means that the sides are proportional to each other. The ratio of CE to AC is 24/8 which is 3. That means that each length of the small triangle is 3 times smaller than the same side on the larger triangle.

Answer: 10

Step-by-step explanation:

(AP3X

Answer:

Step-by-step explanation:

The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.

So the maximum value must be less than 12. What's the smallest x could be?

well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?

5 + y > 7

5 - 5 + y > 7 - 5

y > 2

So the range    is  2 < x < 12

How else could you write this?

2 < x

x < 12 is one way.

Answer:

  3 solutions: 1368, 5364, 9360

Step-by-step explanation:

In order to be divisible by 36, the number must be divisible by 9 and by 4. The number will be divisible by 9 if the sum of its digits is divisible by 9. 36 already has a digit sum of 9, so the two added digits must sum to 9.

The number will be divisible by 4 if the least-significant digit is a multiple of 4. That is, it must be 0, 4, or 8. Then the corresponding most-significant digits must be 9, 5, or 1.

The three solutions are ...

  1368 = 38 · 36

  5364 = 149 · 36

  9360 = 260 · 36

Answer:The vertex is

(0,7)

Sometimes we have problems with the easier questions because it's not exactly in the form we're used to. Normally for a quadratic, you would complete the square to find the vertex. But this quadratic is already in vertex or standard form:

f(x)=−(x−0)2+7

Make sure to ignore .79, because it is unnecessary information.

Answer:

Step-by-step explanation:

Given

Natoy's rectangular swimming pool has the length of 3m more than thrice its

width.

Width=w

Length =3w+3

So

Area of the rectangular swimming pool=length×width

216=(3w+3)×w

216=3w^2+3w

3w^2+3w-216=0

3(w^2+w-72)=0

W^2+w-72=0

W^2+(9-8)w-72=0

W^2+9w-8w-72=0

W(w+9)-8(w+9)=0

(W+9)(w-8)=0

Sotwo value of w are 8,-9

We take positive value for rectangular swimming so we take w=8m

Width=8m

Length=3×8+3

= 24+3

=27m

Option 2

Step-by-step explanation:

[tex]2 \frac{2}{13} + \frac{15}{13} =[/tex] [tex]2 \frac{2}{13} + 1 \frac{2}{13} = 3 \frac{4}{13}[/tex]

Answer: The answer is option 2. 3 4/13

Step-by-step explanation:

2 2/13 + 15/13 =  2 17/13

17 fits into 13 one time and you're left with 4/13 as a remainder.

Since 17 was able to fit into 13 at least once, you get another whole number making your already existing whole number of 2 into 3.

Thus your answer is 3 4/13. I hope this was a helpful explanation! :)

Answer:

The slope is 3

y-intercept is -16

Step-by-step explanation:

Let's start by using the slope formula, [tex]m=\frac{y2-y1}{x2-x1}[/tex]

plug in the points for the relating x and y and solve,

[tex]m\frac{5-2}{7-6}[/tex]   this simplifies to [tex]\frac{3}{1}[/tex]  or "3"

we have our slope: 3/1 or "3"

the equation needed to find the y-intercept is y=mx+b

We will need to solve for "b" to figure out the y-intercept.

let's plug in any pair of x and y, i'll just choose (6,2)

2=3(6)+b,   2=18+b,    2-18=18-18+b,     -16=b  

Y-intercept is -16

Answer:

A

Step-by-step explanation:

all triangles equal 180°, it gives you two angles on each triangles. if you add them together and subtract that from 180 you'll get the final angle. the angles on both triangles Are 45,63, and 72. (they add up to 180) and because both triangles have two angels that are the congruent. they are similar by the Angle angle postulate.

Answer:

constant

Step-by-step explanation:

3 is the coefficient, b is the variable, 4 and 7 are the constants.

Answer:

See below

Step-by-step explanation:

It seems to be a typo.

[tex]f(x)=2x-31+2[/tex]

[tex]f(x)=2x-29[/tex]

The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.

[tex]0=2x-29[/tex]

[tex]x=\dfrac{29}{2}[/tex]

Once there are alternatives with two values, your function  is probably a quadratic function.

[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.
