Answer:

5 or -8

Step-by-step explanation:

[tex](3 \times x) + x {}^{2} = 40[/tex]

[tex]3x + {x}^{2} = 40[/tex]

[tex] {x}^{2} + 3x - 40 = 0[/tex]

using factorization method

[tex]( {x}^{2} + 8x) ( - 5x - 40) = 0[/tex]

[tex]x(x + 8) - 5(x + 8) = 0[/tex]

[tex](x - 5)(x + 8) = 0[/tex]

[tex]x - 5 = 0[/tex]

or

[tex]x + 8 = 0[/tex]

[tex]x = 5[/tex]

or

[tex]x = - 8[/tex]

Step-by-step explanation:

d = √(x2-x1)²+(y2-y2)

d = √((-8-(-1)² - (3-3)²

d = √ (-7)²-0

d = √49

Answer:

-(x-8)*(x+7)

Step-by-step explanation:

Use the commutative property

-× to the power of 2 + x+ 56

-x to the power of 2 + 8x-7x+56

-xx(x-8)-7x+56

-x*(x-8)-7(x-8)

factor out -(x-8)

-(x-8)*(x+7)

Answer: The answer is 56+−1^2

Answer:  Approximately 21.667 km

This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.

======================================================

Work Shown:

20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.

distance = rate*time

distance = (65 kph)*(1/3 hr)

distance = (65*1/3) km

distance = (65/3) km

distance = 21.667 km which is approximate

Answer:

Distance rate=Rate x Time

Distance= (75 km/h) 20 mins

Convert 20 mins in hours= 1/3 h

Distance= (75 km/h) (1/3 h)= 25 km.....

Step-by-step explanation:

D = b² - 4ac

D = 10² - 4 · 3 · 2

D = 100 - 24

D = 76

D = (-5)² - 4 · 1 · (-4)

D = 25 - (-16)

D = 26 + 16

D = 42

D = 7² - 4 · 1 · (-8)

D = 49 - (-32)

D = 49 + 32

D = 81

D = 0² - 4 · 1 · (-9)

D = 0 - (-36)

D = 36

D = (-6)² - 4 · 5 · 10

D = 36 - 200

D = - 164

Answer:

She should get a speeding ticket. The speed limit is 60mph and her speed was 78 mph, 18 miles over the speed limit.

Step-by-step explanation:

She drove 117 miles in 90 minutes.

117/90 = 1.3 miles per minute

1.3 miles x 60 minutes = 78 mph

Step-by-step explanation:

I think you are missing the square root signs or so in the answer options.

the distance between 2 points is calculated by using Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse of the triangle and the distance between the points, which are the end points of the Hypotenuse.

a and b are the legs and enclose the 90 degree angle. they are the differences of the x and y coordinates between the 2 points.

so,

distance² = (1 - -7)² + (6 - 3)² = 8² + 3² = 64+9 = 73

=>

distance = sqrt(73)

Answer:

[tex]-8x^9[/tex]

Step-by-step explanation:

We can split up the exponent into multiple products: [tex](-2x^3)^3=(-2)^3*(x^3)^3[/tex].

We know that [tex](-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8[/tex].

We also know that [tex](x^3)^3=x^{3*3}=x^9[/tex].

So, our answer is [tex]\boxed{-8x^9}[/tex] and we're done!

Since it's an angle on a straight line, the value of angle 2 is 23.25°

Angle 1 = m

Angle 2 = m - 27

Angle 3 = 2m + 6

It should be noted that the sum of angles in a straight line is equal to 180°, therefore we need to equate all the angles given to 180°. This will be:

m + (m - 27) + (2m + 6) = 180°

m + m - 27 + 2m + 6 = 180°

4m = 180° + 27° - 6°

4m = 201°

m = 201/4

m = 50.25°

Therefore, angle 2 will be:

m - 27 = 50.25 - 27 = 23.25°

Answer: A

Step-by-step explanation:

Answer:

look in explanation

Step-by-step explanation:

Seeing as most of your answers are wrong, I'll start from the beginning.

a rational number is a number that can be expressed as a fraction.

an integer is a  whole number.

an irrational number is a number that cannot be expressed as a fraction.

an integer is also always a rational number.

Using this, we can sort the values.

-77/11 can be simplified as -7, which is an integer.

the square root of 144 is 12, which is an integer.

0.25 is a decimal that can be expressed as a fraction, which makes it a rational number that is not an integer.

the square root of 20 is a value that cannot be expressed as a fraction, which makes it irrational.

17/4 is a fraction that is not a whole number, which makes it a rational number but not an integer.

finally, 2*the square root of 10 is irrational.
