If angle x is a right angle, meaning 90 degrees, and the right angle is dissected into two angles with one of them being 50 degrees that leaves 40 degrees left to complete the 90 degree right angle
Answer:
5x-2
Step-by-step explanation:
Answer:
(x + 3)(2x + 5)
Step-by-step explanation:
Given
2x² + 11x + 15
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × 15 = 30 and sum = + 11
The factors are + 6 and + 5
Use these factors to split the x- term
2x² + 6x + 5x + 15 ( factor the first/second and third/fourth terms )
= 2x(x + 3) + 5(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x + 5)
![\dfrac{x_1+x_2+\cdots+x_{99}+x_{100}}{100}=51.28](https://tex.z-dn.net/?f=%5Cdfrac%7Bx_1%2Bx_2%2B%5Ccdots%2Bx_%7B99%7D%2Bx_%7B100%7D%7D%7B100%7D%3D51.28)
which means the sum of the 100 numbers must be
I'm not 100% sure this is right but I think this is how you do it
