Answer:
6w⁴ + 8w²
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = x⁺ᵇ
+ve * -ve = -ve
-ve * -ve = +ve
+ve * +ve = +ve
To solve this problem, we will follow the following steps:
1- get rid of the brackets using the distributive property
2- combine like terms
This can be shown as follows:
w²(-4w² - 2) + (-5w²)(-2w² - 2)
w²(-4w²) + w²(-2) + (-5w²)(-2w²) + (-5w²)(-2)
-4w⁴ - 2w² + 10w⁴ + 10w²
w⁴(-4+10) + w²(-2+10)
6w⁴ + 8w²

Answer:
no. of senior citizens=x
no.of other people=7-x
cost=30=k(7-x)+(k/2)x. k is the cost of a ticket
k(7-x+x/2)
k(7-x/2)-30=0
k=60/(14-x)
now do trial and error substitution for (x<7) until u get a whole number for k also (k<30). if you have the skills you can suggest the number yourself
ie x= 2, k=5$
1. (-4)² = 16
2. Volume
3. 19.2
4. Composite
5. Mean=6
Mode=5
6. ?
7. ?

Given that <span>Lisa had 1,750 stamps and Mark had 480 fewer stamps than Lisa.</span>
Thus, the number of stamps Mark had is 1,750 - 480 = 1,270
Given that <span>Lisa gave some stamps to Mark which makes Mark to have three times as many stamps as Lisa.</span>
Let the number of stamps that Lisa gave to Mark be x, then
Thus, Lisa gave Mark 995 stamps.
Therefore, the number of stamps that Lisa have now is 1,750 - 995 = 755.
