Answer the question below

Answer:

[tex] {x}^{2} + 5x = - 2[/tex]

arrange the equation according to general formula;

General formula: ax² + bx + c = 0

therefore:

[tex] {x}^{2} + 5x + 2 = 0[/tex]

Using the quadratic equation :

[tex]x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ [/tex]

a » 1, b » 5, c » 2

substitute:

[tex]x = \frac{ - 5± \sqrt{ {5}^{2} - (4 \times 1 \times 2) } }{(2 \times 1)} \\ \\ x = \frac{ - 5± \sqrt{17} }{2} [/tex]

therefore solutions are;

[tex]{ \boxed{ \boxed{x_{1} = \frac{ - 5 + \sqrt{17} }{2} }}} \: \: and \: \: { \boxed{ \boxed{x_{2} = \frac{ - 5 - \sqrt{17} }{2} }}}[/tex]

x is -0.438 and -4.562

Answer:

6 sq.cm

Step-by-step explanation:

base = 4 cm

height = 3 cm

[tex]Area =\dfrac{1}{2}* \ base * \ height\\\\= \dfrac{1}{2}*4 * 3\\\\= 2 *3\\\\ 6 \ cm^{2}[/tex]

5 m/s · 12 s = 5 m · 12 = 60 m

Answer: in 12 seconds that car has gone 60 metres.

Answer:

A car travels at a constant rate of 5 metres per second.

That means that for every second,the car travels 5m/s.

The question is asking you for how far the car travelled after 12 seconds.Muntiply 12 to bottom and top.

5m/1s*12/12=60/12

The car travels 60 metre in 12 seconds

Answer:

Question 1: c) 12.5 m/s

Question 2: a) The object is not moving.

Step-by-step explanation:

Question 1: 100(m) divided by 8(s) equals 12.5(m/s)

So she goes 12.5 meters per second (m/s).

Question 2: Distance = x variable (horizontal) because the distance depends on the time. Time = y (vertical) because the time is independent.

If the points on the distance or x axis stay the exact same while the time or y axis continues to change, this will lead to a straight horizontal line on a graph and mean that whatever it is being measured for distance, is staying still or 'constant'.

Step-by-step explanation:

-12x+7=29

or,-12x=-29-7

or,-12x=36

or,x=-36+12

x=-24

Answer:

She had 3.65 or 3 and 13/20

Step-by-step explanation:

4 and 1/4 of a cup in decimal form is 4.25. we know that 3/5 is .60  .Just do 4.25 minus .60

Step-by-step explanation:

we would calculate the line of sight between the 2 lasers.

then we would create a line that goes through the middle point between the 2 lasers and is perpendicular to the line between the lasers. if we are lucky, then "You" is on the same perpendicular line. if not, we need to shift our starting point to a point where the perpendicular line hits the wall of the room.

by following that perpendicular line precisely, we we always have the same distance from both lasers.

This is the number 27 thousand

Answer:

(5z-6w)(5z+6w)

Step-by-step explanation:

Hi there!

We're given the expression 25z²-36w² and we want to factor it.

The expression written as a difference of squares. The difference of squares is given as a²-b²=(a-b)(a+b)

Let's label the values of what is a² and b², and then try to determine what a and b are from that information

[tex]a^{2}=25z^2\\b^2=36w^2[/tex]

Alright then! Let's square root both sides to find what a and b are

[tex]\sqrt{a^2}=\sqrt{25z^2[/tex]

Which then means:

a=5z

And then for b:

[tex]\sqrt{b^2}=\sqrt{36w^2}[/tex]

b=6w

Now substitute those values into the formula

a²-b² = (a-b)(a+b)

[tex]25z^{2}-36w^2=(5z-6w)(5z+6w)[/tex]

Hope this helps!

Answer:

the answer for this questionis 93(68+7)

Answer:

Step-by-step explanation:

What do you know about y?

Nothing. It could be odd or even. You can't take the chance. So you need to start your list with 2y

That means that 2y + 2 is the second member in your list

2y + 4

2y + 6

2y + 8

2y + 10

But notice you only have 5 numbers. 2y + 10 cannot be the answer.

The answer must be 2y + 20

Answer:

$850

Step-by-step explanation:

washer + dryer = $950

if washer cost=>$100

Therefore; the value of the dryer should be x

$100+x=$950

x=$850

The dryer cost is =>$850

Answer:

The dryer is $425.

Step-by-step explanation:

Washer = 100 + Dryer

Set up an equation:

Variable x = dryer

x + x + 100 = 950

x + x = 850

2x = 850

x = 425

Dryer = 425

Bonus answer:

Washer = 100 + x

Washer = 100 + 425

Washer = 525

Check your work:

Washer + Dryer = 950

525 + 425 = 950

950 = 950

Correct!

Step-by-step explanation:

Since the discs have the same thickness, we will think about the areas.

Let say x the new radius:

[tex]\pi*5^2+\pi*20^2+\pi*40^2=\pi*x^2\\\Longrightarrow\ 5^2+20^2+40^2=x^2\\\\\Longrightarrow\ 2025=x^2\\\\\Longrightarrow\ x=\sqrt{2025} =45[/tex]
