Answer with explanation:

Pascal Triangle is Associated with finding the value of nth power of sum or difference of two variables.

The Expression

                (a\pm b)^n, has n+1 , terms.

1-(a+b)^0=1\\\\2-(a+b)^1=a+b\\\\3-(a+b)^2=a^2+2 a b+b^2\\\\4-(a+b)^3=a^3+3a^2b+3ab^2+b^3\\\\5-(a+b)^4=a^4+4a^3b+6a^2b^2+4ab^3+b^4\\\\.......

Now expressing the expression in the form of Pascal's Triangle

                                            1

                                        1                1

                               1              2(1+1)               1

                          1            3(2+1)               3(2+1)            1

                 1            4(3+1)              6 (3+3)             4(3+1)         1

        1         5 (4+1)            10(6+4)            10 (6+4)            5(4+1)       1

1      6(5+1)       15(10+5)      20 (10+10)        15(10+5)        6(5+1)       1

1   7(6+1)   21 (15+6)    35 (20+15)  35(20+15)    21(15+6)  7(6+1)       1

Eight Row is Required to expand the expression →→

      (2x^3+3y^2)^7

Shawna and her best friend Keisha go shopping. The function p(x) = 3x4 + 2x3 − 4x2 + 21 represents how much money each girl spen
tino4ka555 [31]

Answer:

$69

Step-by-step explanation:

Given the amount of money each girl spent based on the number of hours they were shopping modeled by the function p(x) = 3x4 + 2x3 − 4x2 + 21

To get how much they spend together if each go shopping for 2hours, we will substitute x = 2 into the given function as shown:

p(2) = 3(2)⁴ + 2(2)³ − 4(2)² + 21

p(2) = 3(16) + 2(8) − 4(4) + 21

p(2) = 48 + 16 − 16 + 21

p(2) = 48+21

p(2) = 69

Therefore they spend $69 together

Katyanochek1 [597]

Answer:

120 days

Step-by-step explanation:

Canteen A = 12 days

Canteen B = 8 days

Canteen C = 10 days

How many days later will all three canteen serving noodles soup again?

To find the number of days all 3 canteens will serve food again, find the lowest common multiples of all 3 canteens

Canteen A = 12 days

34, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Canteen B = 8 days

16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120

Canteen C = 10 days

20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130

The lowest common multiple of 12 days, 8 days and 10 days is 120 days

The next day all 3 canteens will serve soup together again is the next 120 days

larisa86 [58]

168/3 = 56

<em>Therefore, Chad is driving the car in 56 mph.</em>

672/56 = 12

<em>Therefore, Chad drives 672 miles in 12 hours.</em>

308/11 = 28

<em>Therefore, Chad drives 28 miles per gallon of gas.</em>

672/28 = 24

<em>Therefore, Chad uses 24 gallons of gas to drive 672 miles.</em>
