Answer:
(x-4)(x+5)
Step-by-step explanation:
Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)
Answer:
Geometric proof in explanation.
Step-by-step explanation:
Draw an equilateral triangle.
A equilateral triangle has it's sides all congruent and all it's angles measures 60 degrees.
We are going to draw a line segment to cut the equilateral triangles into two congruent right triangles. I will do this in the attachment with p being positive.
You can see we will get 30-60-90 triangles.
We don't need to find the adjacent measurement to the angle whose measurement is 30 degrees since sine is opposite over hypotenuse.


Answer:
10x^2 + 10x + 1 - 3/(5x - 4),
Step-by-step explanation:
Long Division:
10x^2 + 10x + 1 <------------------------- Quotient
5x - 4 ) 50x^3 + 10x^2 - 35x - 7
50x^3 - 40x^2
50x^2 - 35x
50x^2 -40x
5x - 7
5x - 4
-3 <-------------------Remainder
Answer:
3 x 5 is 15 so it would be 3:15
5 x 5 is 25 so it would be 5:25
Step-by-step explanation:
Just multiply by 5 for each one
3 x 5 is 15 so it would be 3:15
5 x 5 is 25 so it would be 5:25
