Answer:

[tex]\textsf{D.} \quad x=4 \pm \sqrt{17}[/tex]

Step-by-step explanation:

Rearrange the equation so it equals zero:

[tex]\begin{aligned} x^2+4 & =8x+5 \\ \implies x^2+4-8x-5 & = 0\\x^2-8x-1&=0\end{aligned}[/tex]

Now use the quadratic formula to solve for x:

[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when }\:ax^2+bx+c=0[/tex]

[tex]a=1, \quad b=-8, \quad c=-1[/tex]

[tex]\implies x=\dfrac{-(-8) \pm \sqrt{(-8)^2-4(1)(-1)}}{2(1)}[/tex]

[tex]\implies x=\dfrac{8 \pm \sqrt{68}}{2}[/tex]

[tex]\implies x=\dfrac{8 \pm \sqrt{4\cdot 17}}{2}[/tex]

[tex]\implies x=\dfrac{8 \pm \sqrt{4}\sqrt{17}}{2}[/tex]

[tex]\implies x=\dfrac{8 \pm 2\sqrt{17}}{2}[/tex]

[tex]\implies x=4 \pm \sqrt{17}[/tex]

Answer:

The only complete ordered pair in the given table is:

5 months → $60 saved

Therefore, to determine the relationship between the variables, divide the amount saved by the number of months:

[tex]\implies \sf \dfrac{Amount\:saved}{Number\:of\:months}=\dfrac{\$60}{5}=\$12[/tex]

So we can assume that $12 is saved each month.

To complete the table:

⇒ 3 × $12 = $36

⇒ $72 ÷ $12 = 6

⇒ 10 × $12 = $120

Completed table:

[tex]\large\begin{array}{| c | c |}\cline{1-2} \sf Times\:(month) & \sf Amount\:Saved\: (\$) \\\cline{1-2} 3 & 36 \\\cline{1-2} 5 & 60 \\\cline{1-2} 6 & 72 \\\cline{1-2} 10 & 120 \\\cline{1-2} \end{array}[/tex]

Step-by-step explanation:

here,

principal (p)=£6000

Rate (R)=. 3.4%

time (t)=3 yrs

now,

total investment is compound amount i.e CA

here,

[tex]CA = p(1 + \frac{r}{100} ) ^{t} [/tex]

=£6000(1+3.4/100)^3

=£6633.044

here he will get his total investment as £6633.044 in compound interest of 3.4%

Using proportions, considering the amount she received from each person, it is found that Annie had 30 sweets originally.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, we have that:

The final amount was of 63, hence:

1.4 x 1.5 x n = 63

n = 63/(1.4 x 1.5)

n = 30.

Answer:

[tex]y = - 2 |x - 2| + 4[/tex]

Step-by-step explanation:

as the function moved to the right 2 steps, and up 4 steps

Step-by-step explanation:

Here in the given figure b and 30° are alternate to each other so it can be name as alternative angle....

b = 30°

Now...

a + 30° = 180° ( being supplementary angle )

a = 180° - 30°

a = 150°

Now the value of c will be 150° being corresponding

angle with a

c = 150°

z = 60° ( being alternative angle )

Now let's find the value of x.....

here ,

60° + 50° + x = 180° ( the sum of interior angle of triangle is 180°

x = 180° - 110°

x = 70°

Now...

y = 70° ( alternative angle )

Answer:

15, 2

Step-by-step explanation:

Number one: 15

Number two: 2

Well 15 is 13 more than two meaning this is correct.

By eliminating numbers, I was able to find a range of possible numbers which eliminated all the others. Then using that range I found out the number.

The first number is 2 and the second number will be 15.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

There are two numbers that add up to 17.

If one number is 13 more than the other.

Then the two numbers will be

Let the first number be x. Then the second number will be x + 13

x + x + 13 = 17

  2x + 13 = 17

         2x = 4

           x = 2

The first number is 2 and the second number will be 15.

Answer:

113.1 inches

Step-by-step explanation:

The area of a circle can be calculated using the formula [tex]\pi r^{2}[/tex], with r being the radius of the circle.

On this circle, the radius is 12 inches, making the area of the entire circle [tex]\pi 12^{2} =\pi 144[/tex], which is about 452.39.

The shaded area of the circle is 1/4 of the circle, so we use the equation [tex]\frac{452.39}{4}[/tex] to get an area of 113.1 inches.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.

A.) The value of n can be found by equating XY and XZ together,

XY = XZ

9n + 12 = 15n - 6

12 + 6 = 15n - 9n

18 = 6n

n = 3

Hence, the value of n is 3.

The length of different legs of the triangle is,

B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39

C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39

Hence, the length of the legs XY and YZ is equal to 39 units.

157.5 square feet is the area of the roof.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that the roof of a clock tower is a pentagonal pyramid.

a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point

Each side of the base is 7 ft long.

The slant height is 9 ft.

We need to find the  area of the roof.

The expression is rewritten in standard form and they are not the same due to the negative.

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

Both (x−3)(x+3) and (3−x)(3+x) contain a sum and a difference and have only 3 and x in each factor.

Let see the equation formed by the factor;
