Simplify the expression below.<br> <br> (12s4−6s2+4s)+(6s4−4s+27)−(4s4+s2+12)

Rama09 [41]

Answer:

=14s4−7s2+15

Step-by-step explanation:

Steps:

1: Distribute the Negative Sign

=12s4−6s2+4s+6s4−4s+27+−1(4s4+s2+12)

=12s4+−6s2+4s+6s4+−4s+27+−1(4s4)+−1s2+(−1)(12)

=12s4+−6s2+4s+6s4+−4s+27+−4s4+−s2+−12

2: Combine Like Terms

=12s4+−6s2+4s+6s4+−4s+27+−4s4+−s2+−12

=(12s4+6s4+−4s4)+(−6s2+−s2)+(4s+−4s)+(27+−12)

=14s4+−7s2+15

Answer: =14s4−7s2+15

Holli's house is located at (−1, 4). She can walk in a straight line to get to Jedd's house. A fast food restaurant is located a

GrogVix [38]

Answer:

The coordinates of Jedd's house is (-5, 0)

Step-by-step explanation:

Given;

Location of Holli's House = (−1, 4)

Location of fast food restaurant = (−3, 2)

To Find:

The coordinate of Jedd's house.

Solution:

If the distance between the two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is divided by the point (x,y) in the ratio of m : n then

$x=\frac{x_{1}n+x_{2}m}{m + n}$

$y=\frac{y_{1}n+y_{2}m}{m + n}$

Hollis house is located at (-1 , 4)

So, $(x_{1},y_{1}) = (-1 , 4)$

She walks in a straight line to get to Jedds house

The restaurant is located at (-3 , 2) and partitions the way from

(x , y) = (-3 , 2)

The ratio of Hollis house to Jedds house is 1 : 1

(m : n) = 1 : 2

Lets consider that Jedds house is located at $(x_{2},y_{2})$

Then $x_2$ will be

$-3=\frac{-1(1)+x_{2}(1)}{1+1}$

$-3=\frac{-1 +x_{2}}{2}$

$-3 \times 2=-1 +x_{2}$

$-6 = -1 +x_{2}$

$-6 = -1 +x_{2}$

$-5 = x_{2}$

Now $y_{2}$ will be

$2=\frac{4(1)+y_{2}(1)}{1+1}$

$2=\frac{4+y_{2}}{2}$

$2 \times 2=4+y_{2}$

$4 = 4+y_{2}$

$4 - 4 = y_{2}$

$y_{2} = 0$

∴ The coordinates of Jedd's house is (-5, 0)

Paladinen [302]

Answer:

$7\frac{1}{8}$

Step-by-step explanation:

Multiply across.

$(7\frac{1}{6})(\frac{3}{4})=7\frac{3}{24}$

Then Simplify.

$7\frac{3}{24}=7\frac{1}{8}$

xenn [34]

<span>There are 47,124 different committees you can select.

Explanation:
The number of combinations of 9 teachers taken 3 at a time is given by
</span> $_9C_3=\frac{9!}{3!6!}=84$ <span>

The number of combinations of 34 students taken 2 at a time is given by
</span> $_{34}C_2=\frac{34!}{2!32!}=561$ <span>

Together this makes 84*561 = 47124 combinations.</span>
