log_a a^x = x\qquad \qquad \boxed{a^{log_a x}=x}\\\\

pH=-log(H+)\qquad \stackrel{pH}{7.2}=-log(H+)\implies -7.2=log_{10}(H+)
\\\\\\
10^{-7.2}=10^{log_{10}(H+)}\implies 10^{-7.2}=H+\implies \cfrac{1}{10^{7.2}}=H+$

Hello there!

Number 1 is C (11, 4) Image is below

I don't know number 2, so so sorry!

Number 3 is A. 36 The formula for perimeter of a rectangle is (2 * base) + (2 * height)
The base = 13
The height = 5

(5 * 2) + (13 * 2)

10 + 26 = 36

Number 4 is 23 units.

I hope I was of assistance!
