Step-by-step explanation:
The given measurements are:
16 m, 21 m, 39 m
We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.
Therefore, it is not possible to form a triangle with given measurements.
Answer:
1. Expand the expression.
x^8+24x^7+252x^6+1512x^5+5670x^4+13608x^3+20412x^2+17496x+6561
2. (x+3)^5
Use the Binomial Theorem.
x^5+5x^4⋅3+10x^3⋅3^2+10x^2⋅3^3+5x⋅3^4+3^5
Simplify each term.
x^5+15x^4+90x^3+270x^2+405x+243

Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.
Think of it like this, if there are 13 cards numbered 1-13 and you need to find the probability of pulling a multiple of 3.
Then start by laying out all your options.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
Then find all of the multiples of 3
3, 6, 9, 12
There are 4 multiples of 3 out of all of the cards so you have a 4 out of 13 chance to pull a card with a multiple of 3 on it.
Answer = 4/13
Question one: 430=83+15x
