Step-by-step explanation:

\frac{1}{2} x + 3 =  - 1 \\  \frac{x}{2}  + 3 =  - 1 \\  \frac{x}{2}  + 3 - 3 =  - 1 - 3 \\  \frac{x}{2}  = -  4 \\  \frac{x}{2}  \times 2 =  - 4 \times 2 \\ x =  - 8

What's the area of the triangle with 9mm 76mm 100mm
svlad2 [7]

9514 1404 393

Answer:

  342 mm²

Step-by-step explanation:

The triangle shown has a base of 9 mm and a height of 76 mm. Its area is ...

  A = 1/2bh

  A = (1/2)(9 mm)(76 mm) = 342 mm²

The triangle shown has an area of 342 mm².

_____

<em>Additional comment</em>

The other leg of the right triangle with one leg 76 mm and hypotenuse 100 mm will be about 65 mm. The base shown is 9 mm, so any triangle with the dimensions shown will be a fairly skinny obtuse triangle, not the acute triangle in the picture. (This makes us suspect an error: the 9 mm dimension maybe should be 90 mm.)

G (x) = x + 1 (fog) (x) = x 2 + 3x + 1 ⇒ (fog) (x) = x 2 + 3x + 1 ⇒ f (g (x)) = x 2 + 3x + 1 ⇒ f (x + 1) = x 2 + 3x + 1 Eg x + 1 = p, then x = p - 1. ⇒ f (p) = (p - 1) 2 + 3 ( p - 1) + 1 ⇒ f (p) = p 2 - 2p + 1 + 3p - 3 + 1 ⇒ f (p) = p 2  + p - 1 So f (x) = x 2  + x - 1 - ->
