Answer:

3 & 4

Step-by-step explanation:

Perfect Squares Squares:

1, 4, 9, 16, 25.

15 is in between 9 and 16 which rooted is 3 and 4 so 15 falls between the perfect squares of 3 and 4. Another answer would be from 1 & 10 but I think it only asks for one answer. If they do, the best answer is between 3 & 4.

The answer is 7/5

Answer: [tex]x= -4+ \sqrt{23}[/tex] , or [tex]x= - 4 -\sqrt{23}[/tex]

Step-by-step explanation:

Let's solve your equation step-by-step.

[tex]x^2+8x=7[/tex]

The coefficient of 8x is 8. Let b=8.

Then we need to add (b/2)^2=16 to both sides to complete the square.

Add 16 to both sides

x^2+8x+16 = 7+16

x^2 + 8x+ 16= 23

Factor left side.

(x+4)^2 = 23

Take the square root.

[tex]x+4 = +/- \sqrt{23}[/tex]

Add -4 to both sides.

Answer:

C

Step-by-step explanation:

SA=pi*r^2+pi*r*s

SA=3.14*3^2+3.14*3*8

SA=3.14*9+3.14*24

SA=103.62

SA= about 104 inches

Aubrey included the base (you can't put on a hat that has a bottom), the right work should be:

SAhat=pi*r*s

SAhat=3.14*3*8

SAhat=3.14*24

SAhat=75.36

SAhat= about 75

Thus, answer is C

Step-by-step explanation:

In triangle ABC, DE || AC

Therefore by basic proportionality theorem:

[tex] \frac{BD}{DA} = \frac {BE}{EC} \\\\

\therefore \frac{4}{8} = \frac {BE}{9} \\\\

\therefore \frac{1}{2} = \frac {BE}{9} \\\\

\therefore BE = \frac{9}{2} \\\\

\therefore BE = 4.5\\

\because BC = BE + EC \\

\therefore BC = 4.5 + 9\\

Answer: x² + 5x = 3

Step-by-step explanation:Step-by-step explanation:

The rectangle has been divided into a square and three rectangles.

The area of

a square = (x)(x) = x²

a rectangle #1 = (2)(x) = 2x

a rectangle #2 = (3)(x) = 3x

a rectangle #3 = (2)(3) = 6

The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore we have the equation:

x² + 2x + 3x + 6 = 9     subtract 6 from both sides

x² + 5x + 6 - 6 = 9 - 6

x² + 5x = 3

The equation is proven.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

The rectangle has been divided into a square and three rectangles.

The areas are;

square = (x)(x) = x²

rectangle 1 = (2)(x) = 2x

rectangle 2 = (3)(x) = 3x

rectangle 3 = (2)(3) = 6

The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore, we have the equation:

x² + 2x + 3x + 6 = 9

x² + 5x + 6 - 6 = 9 - 6

x² + 5x = 3

Hence, proved.

Answer:

[tex]x+y+z \Rightarrow 2+2+6 = 10[/tex]

Step-by-step explanation:

First we have to factor the equation:

[tex]6xyz+30xy+21xz+2yz+105x+10y+7z=812[/tex]

The commom factor of first three terms and [tex]105x[/tex] is [tex]3x[/tex]. Note that [tex]105x=3x(35)[/tex]

[tex]3x(2yz+10y+7z+35)+2yz+10y+7z=812[/tex]

[tex]3x(2yz+10y+7z+35)+(2yz+10y+7z)=812[/tex]

In order to have two equal factors add 35 both sides:

[tex]3x(2yz+10y+7z+35)+(2yz+10y+7z+35)=847[/tex]

Let's factor [tex](2yz+10y+7z+35)[/tex]

[tex](2yz+10y+7z+35) \Rightarrow 2y\left(z+5\right)+7\left(z+5\right) \Rightarrow \left(z+5\right)\left(2y+7\right)[/tex]

Now we have:

[tex]3x(z+5)\left(2y+7\right)+\left(z+5\right)\left(2y+7\right)=847[/tex]

[tex](3x + 1) (2y + 7) (z + 5) = 847[/tex]

Now it is the interesting part: You have to figure out that 3 numbers multiplied by each other will result in 847.

We have [tex]847 = 7 \cdot 11 \cdot 11[/tex]

Let's try

[tex]2y+7=7\\2y=0[/tex]

I will stop right here. This is not true.

Let's try then

[tex]2y+7=11\\2y=4\\y=2[/tex]

Now let's try

[tex]z+5 = 11\\z=6[/tex]

Now let's try

[tex]3x+1=7\\3x=6\\x=2[/tex]

Note that in this case I didn't considered [tex]3x+1=11[/tex] because it would not be an integer.

Therefore,

[tex]x+y+z \Rightarrow 2+2+6 = 10[/tex]
