Answer:

$(3x+5)(x+5)$

Step-by-step explanation:

$3x^2+20x+25$

To solve, we will need to factor.

$3x^2+20x+25$

Now we got an answer.

$(3x+5)(x+5)$

This is your answer!

Answer:

(3 x + 5) (x + 5)

Step-by-step explanation:

Factor the following:

3 x^2 + 20 x + 25

Hint: | Factor 3 x^2 + 20 x + 25 by finding factors of 3×25 whose sum is 20.

Factor the quadratic 3 x^2 + 20 x + 25. The coefficient of x^2 is 3 and the constant term is 25. The product of 3 and 25 is 75. The factors of 75 which sum to 20 are 5 and 15. So 3 x^2 + 20 x + 25 = 3 x^2 + 15 x + 5 x + 25 = 5 (3 x + 5) + x (3 x + 5):

5 (3 x + 5) + x (3 x + 5)

Hint: | Factor common terms from 5 (3 x + 5) + x (3 x + 5).

Factor 3 x + 5 from 5 (3 x + 5) + x (3 x + 5):

Answer: (3 x + 5) (x + 5)

The total number of arrangements for all of them to be women is:
C(7, 4) because the order does not matter; we'd still have the same arrangements.

Now, we can simplify this:
$C(7, 4) = \frac{7!}{4!(7 - 4)!}$
$= \frac{5040}{4!3!}$
$= \frac{5040}{24 \cdot 6}$
$= \frac{5040}{144} = 35$

Now, the total number of arrangements, without restriction, is simply: C(12, 4) because we don't care who we pick.

$\text{P(4 women): } \frac{35}{495} = \frac{7}{99}$

Rashid [163]

Answer:

a) The can can hold 24.54 inches³ of pop

b) There will be 22.09 inches³ of pop in the can

c) The cone can hold 7.36 inches³ of pop

Step-by-step explanation:

a) We need to work out the volume of the can, using this equation: volume of a cylinder = πr²h

The diameter is half the radius: r = 1.25 inches
r² = 1.5625
π × 1.5625 × 5 = 24.54369... ≈ 24.54 inches³

b) We will still work out the volume of the can, but the height is 4.5 inches instead of 5 inches:

r² = 1.5625
π × 1.5625 × 4.5 = 22.0893233... ≈ 22.09 inches³

c) The cone will have a height of 4.5 inches and a diameter of 5 inches; the volume of a cone = 1/3(πr²h)

1/3(π × 1.5625² × 4.5) = 7.3631077... ≈ 7.36 inches³

Hope this helps!
