hope it's helpful ❤❤❤

THANK YOU.

Answer:

2x² - 8

Step-by-step explanation:

Given

(x - 2)(2x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 4) - 2(2x + 4) ← distribute both parenthesis

= 2x² + 4x - 4x - 8 ← collect like terms

= 2x² - 8

Answer:

The food will last for 10 days

Step-by-step explanation:

Proportions

The amount of food the farmer needs to feed his animals is proportional to the number of animals and to the number of days they are fed.

This can be written as:

Food=k*N*D

Where k is a constant, N is the number of animals and D is the number of days.

We know that the farmer has enough food to feed N=50 animals for D=15 days, thus:

Food=k*50*15=750k

If the same amount of food is used for 50+25=75 animals, then:

750k=k*75*D

Simplifying:

750=75*D

Dividing by 75:

D=10

The food will last for 10 days

Answer:

question 1 = 37 covers , 535 dollars

question 2 = 32 covers , 460 dollars

Expression = 69 covers , 995 dollars

Step-by-step explanation:

You would take the number of covers and multiply it by 15 because 15 dollars is how much they sold each cover for.

and then for the expression wasnt sure what to do but from what i could see you added up the totals.

Hope this helped him :)

also tell me what his snap is BAHA okay lemme stop.

Answer:

x < 13

Step-by-step explanation:

We have an inequality and are asked to solve for x.

Inequality work the same as expressions when it comes to solving for x, the only difference is that when you divide by a negative, the inequality sign changes. Which is not a problem.

4x - 8 < 44

Add 8 to both sides :

4x < 52

Divide 4 from both sides :

x < 13

Answer:

5^2 < 2^5

Step-by-step explanation:

2^5 = 2x2x2x2x2 = 32

5^2 =  5x5 = 25,

since 25 is less than 32, the comparison 5^2 < 2^5 is correct, or 25 < 32

The value of 2^5 is greater than 5^2.

An expression in maths a sentence with a minimum of two numbers or variables and at least one math operation.

Given that the same digits are used for the expression 2^5 and 5^2

2^5 = 32

5^2 = 25

Therefore, 2^5 > 5^2

Hence, The value of 2^5 is greater than 5^2.

Answer:

238m^3

Step-by-step explanation:

Volume = lwh (length times width times height)

so do 4 x 7 x 8 1/2

this gets you 238m^3 (because you have to cube your answer with units)

Answer:

This price was 27% less than the original price...

this means that the price Scott paid was 73% of the original price.

(0.73) * (original price) = 511

solving for original price:  original price = $ 700

Answer: 12 books

Step-by-step explanation:

First you need to remove the cost of shipping from the total amount:

= 75 - 3

= $72

The above is the total amount spent on the books without shipping.

If each book cost $6, the total number of books bought is:

= 72 / 6

= 12 books

The Moon exerts its force of gravity; since it's smaller and lighter than Earth, we would discover we weigh around a sixth of our weight on Earth if we could weigh ourselves on it. One could ask why the Moon doesn't fall on Earth as an apple from the tree.

Answer:

3 miles per hour

Step-by-step explanation:

Speed is defined as the distance covered per unit time, which can be expressed mathematically as follows;

Speed = Distance/Time

The given parameters are;

The length of the circular running track = 1/8 mile

The time it takes Elena to complete a lap = 1/24 hour

Therefore, we have;

Elena's running speed = The distance Elena completes/(The time it takes Elena to complete the given distance)

∴ Elena's running speed = The 1/8 mile track/(1/24 hour)

[tex]Elena's \ running \ speed =\dfrac{\dfrac{1}{8} \ mile }{\dfrac{1}{24} \ hour } = \left (\dfrac{1 }{8} \times \dfrac{24}{1 } \right ) \ \dfrac{mile}{hour} = \dfrac{24}{8} \ \dfrac{mile}{hour} =3 \ mile/hour[/tex]

Elena's running speed = 3 mile per hour.

Answer:

x = 104 degrees

y = 76 degrees

z = 104 degrees

quadrilateral have to add up all of their interior angles to 360 degrees.

x and c are  opposite interior angles.  after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.

Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.

Answer:

m∡x = 104°

m∡y = 76°

m∡z = 104°

Step-by-step explanation:

m∡A ≅ m∡C

m∡B ≅ m∡D

to find m∡B:  2(104) + 2y = 360

                       208 + 2y = 360

                       2y = 152

                        y = 76

m∡z:  180° - 76° = 104°

Answer:

14

Step-by-step explanation:

Answer: 14

Step-by-step explanation:

The greatest common multiple of 2 and 7 is 1, because they are both prime numbers (numbers that cannot be divided by anything other than one or themselves).

Why bother with the greatest common multiple?

There's a very sneaky formula you can do to calculate the LCM with this.

[tex]lcm(a, b) = \frac{|a * b|}{gcd(a, b)}[/tex]

where lcm(a, b) = the least common multiple of integers a and b (1)

a = integer a (2)

b = integer b (7)

gcd(a, b) = greatest common divisor of integers a and b

So let's use it, we have all the available numbers.

[tex]lcm(a, b) = \frac{|2 * 7|}{1} = 14[/tex]

Answer:

The height of her friend is 4.826 feet.

Step-by-step explanation:

The length of the shadow ([tex]x_{S}[/tex]), measured in feet, is directly proportional to the height of the person ([tex]x_{P}[/tex]), measured in feet. That is:

[tex]x_{P} \propto x_{S}[/tex]

[tex]x_{P} = k\cdot x_{S}[/tex] (1)

Where [tex]k[/tex] is the proportionality constant, no unit.

We can eliminate this constant by constructing this relationship:

[tex]\frac{x_{P,M}}{x_{S,M}} = \frac{x_{P,F}}{x_{S,F}}[/tex] (2)

Where M and F represents Melody and Melody's friend. If we know that [tex]x_{P,M} = 5\,ft[/tex], [tex]x_{S,M} = 7\,ft[/tex] and [tex]x_{S,F} = 6\,ft[/tex], then the height of his friend is:

[tex]x_{P,F} = \left(\frac{x_{P,M}}{x_{S,M}} \right)\cdot x_{S,F}[/tex]

[tex]x_{P,F} = \left(\frac{5\,ft}{7\,ft}\right)\cdot (6\,ft)[/tex]

[tex]x_{P,F} = 4.286\,ft[/tex]

The height of her friend is 4.826 feet.

Answer:

1/2

Step-by-step explanation:

there are 13 cards in each type so

heart or diamond would mean either one so 13 +13=26

26/52

1/2

TOTAL NUMBER OF HEART CARDS= 13

TOTAL NUMBER OF DIAMOND CARDS= 13

PROBABILITY OF AN EVENT

= NUMBER OF FAVOURABLE OUTCOMES

TOTAL NUMBER OF POSSIBLE OUTCOMES

Probability of getting a heart card♥=13/52 =1/4

Probability of getting a DIAMOND card♦= 13/52 =1/4

Probability of getting a heart and a diamond card =26/52 =1/2
