Answer:

38

Step-by-step:

f(-2)=3(-2)^2+(-2)+1                  g(-2)=-2(-2)-1

f(-2)=-6^2+(-2)+1                      g(-2)=4-1

f(-2)=36+(-2)+1                         g(-2)=3

f(-2)=34+1

f(-2)=35

f+g ------- 35+3 ------- 38

For what values of K does x2+kx+9=0
Airida [17]

Answer:

k = 6

Step-by-step explanation:

x {}^{2}  + kx + 9 = 0

here,

a = 1,

b = k

c = 9

now,

D = b {}^{2}  - 4ac

k {}^{2}  - 4(1)(9) = 0 \\   k {}^{2}  - 36 = 0 \\ k {}^{2}  = 36 \\ k = 6

Given that ΔPQR is similar to ΔPTS, which statement MUST be true? A) m∠PST = m∠QPR B) m∠TPS = m∠RPQ C) m∠SPT = m∠PTS D) m∠PRQ =
galina1969 [7]

Answer:

The correct option is B.

Step-by-step explanation:

Two triangle are similar if their corresponding sides are in the same proportion or the corresponding angles are same.

It is given that the ΔPQR is similar to ΔPTS. It means all corresponding angles are same.

\angle R=\angle S

\angle Q=\angle T

\angle P=\angle P

Angle P can be defined as

\angle QPR=\angle TPS

\angle RPQ=\angle TPS

Therefore option B is correct.

\angle PST\neq\angle QPR

\angle SPT\neq\angle PTS

\angle PRQ\neq\angle PTS

Therefore option A, C and D are incorrect.
