Answer:
From the Law of cosines we see that Line AB^2 (or side c^2) equals
AB^2 = a^2 + b^2 -2ab *cos (C)
AB^2 = 6*6 + 7*7 -2*6 * 7 * cos(59)
AB^2 = 85 -84 * 0.51504
AB^2 = 85 - 43.26336
AB^2 = 41.73664
AB = 6.4603900811
AB = 6.5 (rounded)

Answer:
(-16)
Step-by-step explanation:
Let the number = x
11 less than 3 times a number: 3x -11
75 less than the product of minus 1 and the number: (-1)*x - 75 = -x -75
3x - 11 = -x -75
3x -11 +x = -75
4x - 11 = -75
4x = -75 +11
4x = -64
x = -64/4
x = -16
Given:
- a=2
- b=-3
Question:
2a - 4b
Step by step explanation:
Step 1:
2×2-4×(-3)
Step 2:
4-4(-3)
Step 3:
4+12
Step 4:
16
So 16 is correct answer
hope it helped you :)
Answer:
8
Reasoning:
-4 times 8 equal -32
therefore -32/-4 is equal to 8
