Answer:
2(k + 9) = 4
Step-by-step explanation:
Use distributive property.
2 x k = 2k
2 x 9 = 18
Equation:
2k + 18 = 4
Subtract 18 from both sides
2k = -14
Divide both sides by 2
k = -7
Given:
edge 1 = 3x - 4
edge 2 = x² - 1
edge 3 = 2x² - 15
perimeter if x = 4
edge 1 = 3(4) - 4 = 12 - 4 = 8
edge 2 = 4² - 1 = 16 - 1 = 15
edge 3 = 2(4²) - 15 = 2(16) - 15 = 32 - 15 = 17
Perimeter = 8 + 15 + 17 = 40 feet.
Answer:
50 beats/min
