Answer:
The solution for the given expression x ix 6.
Step-by-step explanation:

Solution:
Step 1: Adding (-4x) on both sides


Step 2: Adding (5) on both sides:


The solution for the given expression x ix 6.
The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
If they pay $28 for 16 jerseys then the total they’d have to play is $448
28 x 16 = 448

Answer:
See below
Step-by-step explanation:
<u>Given function</u>
<u>We can find its factors:</u>
- x³ + 3x² - 7x - 21 =
- x²(x + 3) - 7(x + 3) =
- (x² - 7)(x + 3)
We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)
Also one of zeros of the function is -3
