If -h = 14, then ... h = -14
h - 4 = 10 Therefore, h = 10 + 4 h = 14
The statement "H⁺ plus OH⁻ equals 14" is a misunderstanding of the pH scale. In pure water at 25°C, the concentration of hydrogen ions (H⁺) and hydroxide ions (OH⁻) is equal, and their product results in a constant (Kw = 1.0 x 10⁻¹⁴). Therefore, the pH (which is the negative logarithm of H⁺ concentration) and pOH (the negative logarithm of OH⁻ concentration) add up to 14, but H⁺ and OH⁻ themselves do not equal 14.
Well, let's see . . .-18h = 28Multiply each side by -1 :18h = -28Divide each side by 18:h = -28/18 = -14/9 = -(1 and 5/9)
Surface Area = 2*(L*W + W*H + H*L) = 2*(7*5 + 5*2 + 2*7) = 2*(35+10+14) = 2*59 = 118 square units.

h - 4 = 10 Therefore, h = 10 + 4 h = 14
Area = 1/2*16*14 = 112 square units
h = 0.538462 14 + 5h + 2h = 5h + 28h 14 + 7h = 33h 14 + 7h - 7h = 33h - 7h 14 = 26h 14/26 = 26/26h 0..538462 = h

h - 25 =< 14 Add '25' to both sides h =< 14 + 25 h =< 39 NB Treat Inequalities like an 'Equals' except when multiplying negative numbers or fractions, whereupon , turn the sign around. Verificstion When h = 38 Substitute 38- 25 = 13 which is less than 14. as required. When h = 40 40 - 25 = 15 > 14 So NOT True.
Surface Area = 2*(L*W + W*H + H*L) = 2*(7*5 + 5*2 + 2*7) = 2*(35+10+14) = 2*59 = 118 square units.
