Answer:

136 cm²

Step-by-step explanation:

I'm going to split the net into:

2x          7 cm by 2 cm rectangles

2x          6 cm by 7 cm rectangles

2x          6 cm by 2 cm rectangles

The 2x means there's 2 of them.

Let's find the area of the 2x 7 cm by 2 cm rectangles:

2*7*2=

4*7=

28 cm²

Let's find the area of the 2x 6 cm by 7 cm rectangles:

2*6*7=

2*42=

84 cm²

Let's find the area of the 2x 6 cm by 2 cm rectangles:

2*6*2=

12*2=

24 cm²

Adding all these areas together gives us the surface area of the net:

28+84+24=136 cm²

Write the equivalent logarithmic equation to 10^a = x+b
MA_775_DIABLO [31]

Answer:

The answer to your question is   log₁₀ x + b = a        

Step-by-step explanation:

General formula

                 Logarithmic function                Exponential function

                           log ₐ b = c                                  b^{c} = a

a = antilogaritm                                               c = exponent

b = base                                                          b = base

c = logaritm                                                     a = power

In your problem

10 = base

a = exponent

x + b = power

Exponential function              log₁₀ x + b = a
