I Need Help With This One

Mathematics
1 answer:
Arisa [49]3 years ago
7 0

Answer:

x = -6  x= -3

Step-by-step explanation:

f(x) = x^2+9x+18

Set equal to 0 to find the zeros

0 = x^2+9x+18

Factor, what numbers multiply to 18 and add to 9

6*3 =18

6+3=9

0= (x+6) (x+3)

Using the zero product property

x+6 =0   x+3 =0

x = -6  x= -3

Find the missing angel ​
kolezko [41]

Answer:

x=25°

Step-by-step explanation:

The given angle is a 90° angle. We know this because of the little square in the corner. This means that both angles must add up to 90°:

x+y=90

Insert the known values:

x+65=90

Solve for x. Subtract 65 from both sides:

x+65-65=90-65\\\\x=25

The missing angle, x°, is 25°.
