Caleb's mother said they will drive 1 /4 hour to get there, and they will drive another 1 /4 hour back. Once they arrive, Caleb's brother will be playing in 3 soccer games. Each soccer game takes 3 4 hour, and there is no break in between games. Calculate how long will they be away from home.

Answers

Answer: They are away for $2(3)/(4)\ hours$ from home.

Step-by-step explanation:

Since we have given that

Time to get there = $(1)/(4)$

Time to get back = $(1)/(4)$

Number of soccer games = 3

Time for each soccer games = $(3)/(4)$

So, total time for 3 games would be

$3* (3)/(4)=(9)/(4)$

So, the time for which they will be away from home is given by

$(1)/(4)+(9)/(4)+\frac{1}4}=(1+9+1)/(4)=(11)/(4)=2(3)/(4)\ hours$

Hence, they are away for $2(3)/(4)\ hours$ from home.

For 1st.
you can solve it by general law or ,
since the coefficient of r^2 = 1
so u should think of 2 number which if u multiple them gives you 27 and sum of them is 12 and those numbers are 9 , 3
so the answer (x+9)*(x+3)
2nd problem :
g^2 - 9 = (g-3)*(g+3)
3rd problem:
2p^3 + 6p^2 + 3p +9
1st divide it into two parts
(2p^3 +6p^2)+ (3p+9)
from the 1st part
take 2p^2 as a common factor and from part 2 take 3 as a common factor and the equation be like
2p^2(p+3) + 3(p+3)
then take (p+3) as a common factor
so (p+3)* ( 2p^2 +3 )

1: (r+3)(r+9). 2: (g+3)(g-2). 3: (2p^2+3)(p+3). FOIL multiply the first, inside, outside, and last terms. add the inside and outside terms together. :)

For f(x) = 3x +1 and g(x) = x2 – 6, find (f- g)(x).

Answers

Answer:

$\boxed{\sf (f-g)(x) = -{x}^(2) + 3x + 7}$

Given:

$\sf f(x) = 3x + 1 \n \sf g(x) = {x}^(2) - 6$

To find:

$\sf (f - g)(x) = f(x) - g(x)$

Factor this expression completely. 8r6 + 27s12

Answers

The factor of the expression 8r⁶ + 27s¹² can be (2r²+3s⁴)(4r⁴-6r²s⁴+9s⁸) after using the identity a³+b³ = (a+b)(a²-ab+b²).

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

= 8r⁶ + 27s¹²

The above expression can be written as:

8r⁶ + 27s¹² = (2r²)³+(3s⁴)³

After applying the identity:

a³+b³ = (a+b)(a²-ab+b²)

= (2r²+3s⁴)(4r⁴-6r²s⁴+9s⁸)

Thus, the factor of the expression 8r⁶ + 27s¹² can be (2r²+3s⁴)(4r⁴-6r²s⁴+9s⁸) after using the identity a³+b³ = (a+b)(a²-ab+b²).
