injection of 50 mg/kg sodium pentobarbital (Sigma), and thoracic aorta was carefully dissected and maintained at 37 C in Krebs solution containing 118.2 mM NaCl, 4.7 mM KCl, 1.2 mM MgSO 4 , 25 mM NaHCO 3 , 1.2 mM KH 2 PO 4 , 1.9 mM CaCl 2 and 11.7 mM dextrose (pH 7.4, 95% O 2 , 5% CO 2 )
Step 1: **Apply the distributive property to the first term:** -3(2 + 4k) = -3 * 2 + (-3) * 4k = -6 - 12k Step 2: **Apply the distributive property to the second term:** 7(2k - 1) = 7 * 2k + 7 * (-1) = 14k - 7 Step 3: **Combine like terms:** (-6 - 12k) + (14k - 7) = -6 - 7 + (-12k + 14k) = -13 + 2k = 2k - 13
