Answer:
x = 9 ⇒ second answer
Step-by-step explanation:
∵ (a + 3)(-2a² + 15a + 6) =
-2a³ + 15a² + 6a - 6a² + 45a + 18 =
-2a³ + 9a² + 51a + 18
∵ (a + 3)(-2a² + 15a + 6) = -2a³ + xa² + 51a + 18
∴ -2a³ + 9a² + 51a + 18 = -2a³ + xa² + 51a + 18
∴ x = 9
Answer:
m∠BOC = 40°
Step-by-step explanation:
Given O A ‾ ⊥ O C ‾ OA ⊥ OC m∠BOC=6x−6 ∘
m∠AOB=5x+8 ∘
Find m ∠ B O C:
This means that: m∠BOC and m∠AOC intersect at a right angle.
Hence:
m∠BOC + m∠AOC = 90°
Step 1
Solving for x
6x - 6 + 5x + 8 = 90°
11x -2 = 90°
11x = 90 - 2
11x = 88
x = 88/11
x = 8
Step 2
Solving for m∠BOC
m∠BOC = 6x - 8
m∠BOC = 6(8) - 8
= 48 - 8
= 40°

Answer:
Lyle and Kyle shot 18 baskets each.
Cliff shot 6 baskets.
Step-by-step explanation:
To figure this out, you have to play around with how many shots Cliff made. You can just plug in reasonable numbers until Lyle and Kyle's baskets match.
If Lyle has to shoot 3 times more than Cliff, you multiply 6 x 3 to get 18.
If Kyle shoots 12 more than Cliff, you add 6 + 12 to get 18.
You know you did it right because in the problem it says Lyle's and Kyle's number of shots are equal.
