What is the answer to this problem<br> 8x-2=-9+7×

Ksenya-84 [330]

8x−2=−9+7x

Simplify:

8x−2=−9+7x

8x+−2=−9+7x

8x−2=7x−9

Subtract 7x from both sides.

8x−2−7x=7x−9−7x

x−2=−9

Add 2 to both sides.

x−2+2=−9+2

x=−7

frozen [14]

Answer:

9 $\sqrt{3}$ cm² or approximately 15.59 cm²

Step-by-step explanation:

Use the formula for the area of an equilateral triangle, A = $\frac{\sqrt{3} }{4}$ a²

Plug in the side length, 6 cm, as a in the formula:

A = $\frac{\sqrt{3} }{4}$ (6²)

A = $\frac{\sqrt{3} }{4}$ (36)

A = 9 $\sqrt{3}$

So, the area of the logo is 9 $\sqrt{3}$ cm² or approximately 15.59 cm²

7. Which dimensions result in the minimum perimeter for a rectangle with area 42.0 cm2?

natali 33 [55]

9514 1404 393

Answer:

7. d. l = 6.48 cm, w = 6.48 cm

8. d. square

Step-by-step explanation:

For a given area, the perimeter can always be shortened by reducing the length of the long side and increasing the length of the short side. When you get to the point where you can't do that, then you have the minimum perimeter. You will reach that point when the sides are the same length: the rectangle is a square.

7. In light of the above, the best dimensions are √42 ≈ 6.48 cm for length and width.

8. In light of the above, the shape is a square.

_____

The attached graph shows the length of one side (x) and the associated perimeter. The other side is 42/x, which will also be 6.48.
