Answer:

x = 9.9

Step-by-step explanation:

<u>Step 1:  Solve for x</u>

<em>Add 2.1 to both sides...</em>

-2.1 - x + 2.1 = -12 + 2.1

-x = -9.9

<em>Multiply both sides by -1...</em>

-x * -1 = -9.9 * -1

x = 9.9

Find the area of the shaded region
PIT_PIT [208]

Answer:

Area of the shaded region= 500inch^2

Step-by-step explanation:

Area of the shaded region= Area of the triangle- Area of the rectangle

Dimensions of the triangle:

Base= 40 inch

Height= 40 inch

Area of a triangle=\frac{1}{2}*Base*Height

           =\frac{1}{2}*40*40\\\\ =\frac{1}{2} *1600\\\\=800 inch^2

Area of the rectangle= Length*Width

Length=30 inch

Width=10 inch

Area:

          = 30*10\\\\=300 inch^2

Area of the shaded region=  800-300= 500 inch^2

Help find the distance between two points?
miv72 [106K]

Answer:

4

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = B(0, 0) and (x₂, y₂ ) = (\frac{\sqrt{6} }{2}, \frac{\sqrt{58} }{2} )

AB = \sqrt{((\frac{\sqrt{6} }{2})^2 } + \{(\frac{\sqrt{58} }{2})^2 }

= \sqrt{\frac{6}{4} } + \frac{58}{4}

= \sqrt{\frac{64}{4} }

= \sqrt{16}

= 4
