Answer 1

Answer:

(p - 3q)/ 5p

Step-by-step explanation:

p^2 - 7pq + 12 q^2

= (p - 3q)(p - 4q)

and

5p^2 - 20 pq = 5p(p - 4q)

The p - 4q is common to both expressions so the answer is

(p - 3q)/ 5p.

Answer 2

Answer:

[tex]\frac{p-3q}{5p}[/tex]

Step-by-step explanation:

Given

[tex]\frac{p^2-7pq+12q^2}{5p^2-20pq}[/tex] ← factorise numerator and denominator

= [tex]\frac{(p-4q)(p-3q)}{5p(p-4q)}[/tex] ← cancel (p - 4q) on numerator/ denominator

= [tex]\frac{p-3q}{5p}[/tex]

If (x + 4)^2 = 49 and x < 0. what is the value of x?

Answers

Answer:

x = -11

Step-by-step explanation:

To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.

-11 + 4 = -7

(-7)^2 = 49

Answer:

x = -11

Step-by-step explanation:

To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.

The cube of a whole number is 48 more
than the square of the same number.
What is the number?

Answers

Answer:

x  = 4

Step-by-step explanation:

Let the number = x

x^3 = x^2 + 48

x^3 - x^2 - 48 = 0

The answer is 4, but I have no method of doing this rigorously. I can just show that it is true.

x^3 = 4^3 = 64

x^2 = 4^2 = 16

64 - 48 = 16

Nicole had the exact amount of money to buy 9 pens.
Instead she bought only 5 pens.
She used the rest of the money to buy 7 notebooks at $1.20 each.
How much money did Nicole have at first?​

Answers

Answer:

18.90$

Step-by-step explanation:

Pen = p

Notes = n

n = 1.20

5p + 7n = 9p

-9p + 5p + 7n = 0

-4p + 7n = 0

-4p + (7*1.2) = 0

-4p + 8.4 = 0

8.4/4 = p

2.1 = p

9p = 9*2.1

9p = 18.90$

A plant is already 12.00 meters tall and it will grow 20 cm every month.what is the plants height after 30 months

Answers

Answer:

18 m

Step-by-step explanation:

Hi there!

We're given:

⇒ The plant is already 12 m tall

⇒ It grows 20 cm every month

First, we must convert everything into the same unit. Divide 20 cm by 100 to convert it to meters:

20 ÷ 100 = 0.2

Now, we can form this equation:

Plant Height = 12 m + (0.2 m × number of months)

Let plant height be h and number of months be m:

[tex]H=12+0.2m[/tex]

To find the plant's height after 30 months, replace m with 30:

[tex]H=12+0.2(30)\\H=12+6\\H=18[/tex]

Therefore, the plant would be 18 m tall.

I hope this helps!

Answer:

25.7

Step-by-step explanation:

PQ=PR-QR

PQ=38.3-12.6

PQ=25.7 cm

Answer: PQ = 25.7 cm

Concept:

Here, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

PR = 38.3 cm

QR = 12.6 cm

Given expression deducted from the segment addition postulate

PQ = PR - QR

Substitute values into the expression

PQ = (38.3) - (12.6)

Simplify by subtraction

PQ = [tex]\boxed{25.7cm}[/tex]

6x10^-3 in standard notation

Answers

Answer:

0.006

Step-by-step explanation:

The number is currently in scientific notation. To change scientific notation into standard notation move the decimal place equal to the number of the exponent. In this case, the exponent is -3. So, move the decimal place 3 digits. Since the 3 is negative, move the decimal to the left. Therefore, 6.0x10^-3 becomes 0.006 because the decimal was moved 3 places to the left. When moving the decimal fill in any empty spaces with zeros.
