Step-by-step explanation:
Expand both factors and collect like term
Using Pascal' triangle with n = 6 to obtain the coefficients
1 6 15 20 15 6 1
Decreasing powers of 1 from to
Increasing powers of 3x from to
= 1. + 6. + 15. + 20. + 15.1² + 6. + 1.
= 1 + 18x + 135x² + 540x³ + 1215 + 1458 + 729
--------------------------------------------------------------------------------------
= 1 - 18x + 135x² - 540x³ + 1215 - 1458 + 729
----------------------------------------------------------------------------------
Collecting like terms from both expressions
+
= 2 + 270x² + 2430 + 1458
----------------------------------------------------
(2)
Using Pascal's triangle with n = 5
1 5 10 10 5 1
Increasing powers of 2x from to
= 1. + 5. + 10. + 10. + 5.+ 1.
= 1 + 10x + 40x² + 80x³ + 80 + 32

Answer:301 watermelons
Find out what is percentage of watermelons in all fruits
a+o+hdm+wtm=100%
a=39%
o=28%
hdm=13%
39%+28%+13%+wtm=100%
wtm=100%-39%-28%-13%
wtm=100%-80%
wtm=20%
Lets find out how many of watermelons are using percentage :
20/100*1505=301
m= if i get the Diagram i will answer
The number is 23.
5n + 7 = 122 Subtract 7 on both sides
5n = 115 Isolate the variable by dividing 5 on both sides
n = 23
