Answer:

- 112 + 100 n

Step-by-step explanation:

$a_{n}$ = $a_{1}$ + (n - 1 )d

~~~~~~~

$a_{1}$ = - 12

d = 100

$a_{n}$ = - 12 + 100( n - 1 )

$a_{n}$ = - 12 + 100n - 100

$a_{n}$ = - 112 + 100 n

$\left(2x-1\right)\left(2x+5\right)$

Step-by-step explanation:

║Given info║:

Factor completely: $4x^2 +8x -5$

Solution~:

Breaking the expression~: $\left(4x^2-2x\right)+\left(10x-5\right)$

Factor out 2x from 4x² -2x : 2x(2x-1)

Factor out 5 from 10x - 5 : 5(2x - 1)

Put together: $=2x\left(2x-1\right)+5\left(2x-1\right)$

Factor out 2x - 1: $=\left(2x-1\right)\left(2x+5\right)$

Why can't a triangle have more than one obtuse angle

vlada-n [284]

An "obtuse" angle is an angle that's bigger than 90 degrees.
So two obtuse angles would add up to more than 180 degrees.

But the three angles inside a triangle always add up to exactly 180 degrees.
So two of them can't be obtuse.
