Answer:

x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21

Step-by-step explanation:

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

4(x+5)^2=21

Step 1: Simplify both sides of the equation.

4x^2+40x+100=21

Step 2: Subtract 21 from both sides.

4x^2+40x+100−21 =21−21 4x^2+40x+79=0

For this equation: a=4, b=40, c=79

4x^2+40x+79=0

Step 3: Use quadratic formula with a=4, b=40, c=79.

x= −b±√ b^2−4ac/2ax

= −(40)+√ (40)^2−4(4)(79)/2(4)

x = 40^2±√ 336/8

x= −5+1/2 √ 21 or x = −5+ − 1/2√ 21

Answer: x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21

Answer:

20 degrees

Step-by-step explanation:

The line has a total of 180 degrees. So, x+100+3x=180. Then, we subtract 100 from both sides to get x+3x=80. Then, x+3x=4x. So, 4x=80 degrees, and so divide by 4 on both sides and you get x=20 degrees.

Given:

The equation is

[tex]x+\dfrac{4}{5}=45[/tex]

To find:

The value of x.

Solution:

We have,

[tex]x+\dfrac{4}{5}=45[/tex]

Isolating the variable, we get

[tex]x=45-\dfrac{4}{5}[/tex]

[tex]x=\dfrac{225-4}{5}[/tex]

[tex]x=\dfrac{221}{5}[/tex]

[tex]x=44.2[/tex]

Therefore, the value of x is 44.2.

Answer:

The equal amount is 525 .

Step-by-step explanation:

Given that,

Eric and his two sister shared amount of money in ratio2:7 respectively.

Amount with Eric = 300

It means,

2x = 300

x = 150

So,

7x = 7(150)

= 1050

As the remaining amount shared equally among the sister. So, the equal amount is 525 .

Responder:

24 días

Explicación paso a paso:

Dado que:

Total de páginas = 288

Número de páginas leídas por día = 12

Número de días que se necesitarán para leer el libro completo:

Total de páginas / número de páginas leídas por día

288/12

= 24

Por lo tanto, a María le tomará 24 días leer el libro completo, si lee 12 páginas del libro por día.

Answer: one-sixth

Step-by-step explanation:

Noah drew the circle which is divided into six equal parts

This shows that cherries must be divided into six persons

each sector of the circle is  [tex]\frac{1}{6}^{th}[/tex] of the whole circle

From this, we can conclude that each person receives  [tex]\frac{1}{6}[/tex]  pound of cherries.

Answer:

36 ÷ 6 = 12

24 ÷ 6 = 4

12 ÷ 6 = 2

Step-by-step explanation:

There are way more numbers that can be divised by 6 but these can be chosen.

Answer:

15.

Step-by-step explanation:

These are:-

12, 18, 24 , ........... 96

There are (96 - 12) / 6 + 1 =

= 14 + 1

= 15.

Answer:

like terms have the same VARIABLES with the same POWER

:)

Answer:

Variables; Powers

Step-by-step explanation:

Like terms have the same variables with the same powers. Eg:-

[tex]3 {x}^{2} \: and \: 9 {x}^{2} [/tex]

These are like terms as they both have the same variables and powers

Answer:

32,768 ways

Step-by-step explanation:

True/ false questions = 5 ; number of options = 2 (True or false)

Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32

Number of Multiple choice questions = 5

Number of options (A - D) = 4 options

Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024

32 * 1024 = 32,768 ways

Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason

Answer:Jason has read  7 mystery novels and Judy has read  17 mystery novels

Step-by-step explanation:

Total number of mystery books read by  Jason and Judy =24

Let Number of mystery books read by Jason=x

and  Number of mystery books read by Judy= 3x-4

So that the total number of book read by both of them will be expressed as

x +(3x-4) =24

x +3x-4 =24

4x=24+4

4x=28

x=28/4=7

There fore  Jason has read  7 mystery novels

and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels

Answer:

R = 10 cm

Step-by-step explanation:

The area of a spherical shape is given by :

[tex]A=4\pi r^2[/tex]

Where

r is the radius of the sphere

ATQ,

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.

The radius of each small bubble is 5 cm

Using the given condition,

[tex]4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm[/tex]

So, the radius of the large bubble is equal to 10 cm.

Answer:

20cm

Step-by-step explanation:

5cm+5cm+5cm+5cm=20cm

Step-by-step explanation:

Answer:

Area = (8 + 2x)² mi²

Step-by-step explanation:

Length of the side of a park = 8 mi

Width of the road around the park = x mi

Length of one side of the park with the road = (8 + 2x) mi

Area of the park with road = (side)²

                                            = (8 + 2x)²

Therefore, combined area of the park and road is (8 + 2x)² square miles.

Answer:

153.9 ft²

Step-by-step explanation:

Given that:

Radius of circular lawn = 7 feets

To obtain the maximum number of square feet of lawn Nichole can expect the sprinkler to cover ; find the area of the lawn

Area of a circle, A = πr²

A = π * 7 * 7

A = 153.93804

Step-by-step explanation:

Answer:

a = 7

Step-by-step explanation:

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

3/5(a+5.25)=7.35

Step 1: Simplify both sides of the equation.

3/5(a+5.25)=7.35

(3/5)(a)+(35)(5.25)=7.35 (Distribute)

3/5a+3.15=7.35

Step 2: Subtract 3.15 from both sides.

3/5a+3.15−3.15=7.35−3.15

3/5a=21/5

Step 3: Multiply both sides by 5/3.

(5/3)*(3/5a)=(5/3)*(21/5)

a=7
