Plz I need some help with 11-12 . My teacher didn’t even explain it correctly so now I’m confused.

rusak2 [61]

Answer:

Step 1: Transpose everything to one side

12. x²+16x+15-10x+4=0

Step 2: Add the like terms

x² + (16x - 10x) + 15 + 4=0

x² + 6x + 19=0

Step 3: Use the quadratic formula to get the value(s) of x.

a=1 b=6 c=19

$x = \frac{ - b + - \sqrt{b {}^{2} - 4ac } {}^{} }{2a}$

therefore, x=... or x

Minchanka [31]

Answer:

72

Step-by-step explanation:

31 -22 = 9

47 -31 = 16

We observe that these are square numbers. The next square number is 25, so we expect the next number in sequence to be ...

47 +25 = 72
