Answer:

x = 9

Step-by-step explanation:

\frac{\frac{1}{5} x+1}{7} =0.4 <------------------ convert the decimal into a fraction

\frac{\frac{x+5}{5} }{7} =0.4 <------------------ simplify the complex fraction

\frac{x+5}{35} =0.4

x+5=14 <------- multiply both sides of the equation by 35

x=14-5 <--- move the constant to the right-hand side and change its sign

x = 9 <---------- subtract the numbers

Find the area of the shape shown below.
Andru [333]

Answer:

10 square units.

Step-by-step explanation:

Remark

No matter how weird it looks, the figure is a trapezoid. It has 2 parallel lines.

The height has 2 right angles, one at each end.

Givens

b1 = 2

b2 = 8

h = 2

Formula

Area = 1/2 * (b1 + b2 ) * h

Solution

Area = 1/2 * (2 + 4 + 2 + 2) * 2    Be sure you understand where all those 2s came from.

Area = 10 square units

Explain why 21i^2 is equivalent to -21
Citrus2011 [14]

Answer:

Step-by-step explanation:

The imaginary number 'i' is equal to the square root of -1. If you were to square the square root, they both cancel and you get -1.

21i^2=21(\sqrt{-1} )^2=21(-1)=-21
