What is all the answers cause i got -98
Answer:
-43K+17
Step-by-step explanation:
(–9k3 + 12k2 + 9) – (10k3 + 3k2 + 4k – 8)
-9.3=-27 10.3=30
12.2=24 3.2=6
=(-27k+24k+9) - (30k+6k+4k-8)
COLLECT LIKE TERMS
=(-3k+9) - (40K-8)
= -3k+9-40k+8
= -43k+17
Answer: x = 8
Step-by-step explanation:
Since, RTS is the equilateral triangle.
Thus, RT= TS = SR
And, 
( By the property of the equilateral triangle.)
Here, Given ∠ RST = (7 x + 4)°
And, ∠ RTS = (8y +12)°
Therefore, (7 x + 4)° = 60°
⇒ 7 x = 56
⇒ x = 8
