Answer 2

(5x² - 13x -28)/(x-4) = (x-4)(5x+7) so x = -7/5  and x = 4 are the two factors of the given polynomial.

What is a factor of a polynomial ?

The factors of a polynomial are those values of x for which the given polynomial satisfies.

According to the given question we have to divide a polynomial            (5x² - 13x -28) by (x - 4).

(5x² - 13x -28)/(x-4) = (x-4)(5x) + (7x - 28).

(5x² - 13x -28)/(x-4) = (x-4)(5x+7).

So, the obtained factor is (5x+7) = 0.

∴ 5x + 7 = 0

5x = -7

x = -7/5 is a factor of the given polynomial and by substituting these value in x.

(5x² - 13x -28)

5(-7/5)² - 13(-7/5) - 28 = 0

5(49/25) + 91/5 - 28 = 0

49/5 + 91/5 - 28 = 0

140/5 - 28 = 0.

28 - 28 = 0

0 = 0     ( hence satisfied that -7/5 is a factor of the given polynomial ).

nick have collection of 80 cars.3/5 of his toys are bus.the rest are cars and bike.the number of cars are the three time the number of bikes.how many cars are there.

Answers

Answer:

24 cars

Step-by-step explanation:

out of 80 toys, 3/5 are buses- 80 * 3/5 is 48 so there are 48 buses

80 - 48 is 32, 32 of the rest of the toys are cars and bikes

we know that there are 3 times as many cars than bikes, so to find out how many cars and bikes there we can do 3n + n, where n is the number of bikes it also equals 4n

32 = 4n; n = 8

there are 8 bikes, so there are 24 cars

Aviv thinks of two numbers between 6 and 50. The highest common factor of his two numbers is 5. The lowest common multiple of his two numbers is 60. Write down the two numbers that aviv is thinking of.

Answers

Answer:

15 and 20.

Step-by-step explanation:

The 2 numbers are both divisible by 5.

Listing numbers whose LCM is 60 and divisible by 5.

20 and 30 :- not this as the HCF is 10.

15 and 20 : - HCF = 5 and LCM = 60.

Aviv is thinking of the numbers 60 and 5.

How to determine the two numbers that aviv is thinking of.

Let's consider the factors of 5 and the prime factorization of 60 to find the two numbers Aviv is thinking of.

The prime factorization of 60 is \(2^2 \times 3 \times 5\).

Since the lowest common multiple of two numbers is the product of their highest powers of prime factors, and we know the lowest common multiple is 60, this suggests that one of the numbers includes \(2^2\), \(3\), and \(5\) as prime factors.

However, we also know that the highest common factor of the two numbers is 5. This means that the second number must include \(5\) as a prime factor.

Putting these pieces together, the two numbers that Aviv is thinking of are \(2^2 \times 3 \times 5 = 60\) and \(5\).

So, Aviv is thinking of the numbers 60 and 5.

Answers

Answer:

not equivalent expressions

Step-by-step explanation:

Expand and simplify both expressions

2x - 3(1.3x - 2.5) - 5.9x + 7.5 ← distribute parenthesis

= 2x - 3.9x + 7.5 - 5.9x + 7.5 ← collect like terms

= - 7.8x + 15

----------------------------------------

3 - 2(- 2.6x + 2.1) - 5.2x - 1.1 ← distribute parenthesis

= 3 + 5.2x - 4.2 - 5.2x - 1.1 ← collect like terms

=  - 2.3

Then the 2 expressions are not equivalent

Answer:

2x-3(1.3x-2.5)=5.9x+7.5

Equivalent Expression

3-2(-2.6x+2.1)=5.2x-1.1

Not Equivalent Expression

Step-by-step explanation:

Solving the first linear expression

2x-3(1.3x-2.5)=5.9x+7.52x-3.9x+7.5=5.9x+7.52x-3.9x-5.9x = 7.5-7.5-7.8x = 0x = 0/-7.8x = 0

Thus, we can say that it's an equivalent expression.

Now Solving the second linear expression

3-2(-2.6x+2.1)=5.2x-1.13+5.2x-4.2= 5.2x-1.15.2x-5.2x = -1.1-3+4.20 ≠ 0.1

Thus, we can say that it's not an equivalent expression.

Answers

The mean value is the sum of the temperature values divided by the total frequency. Hence, the mean value in Fatima's temperature result is -0.75°C

Given the data :

Person 1 :

Sum = (-3 + (-1) + 0 + 2) = - 2

Person 2 :

Sum = (4 + (-4) + 2 + (-3)) = - 1

Person 3 :

Sum = (8 + (-2) + 5 + 1) = 12

Mean value = (Total sum ÷ Frequency)

Mean value = [(-2 + (-1) + 12) ÷ 12]

Mean value = - 9 ÷ 12 = - 0.75

Start by multiplying both sides by k:

[tex](k)r = \frac{2(v - h)}{k} (k)[/tex]

rk = 2(v - h)
