27 Solve for x to the nearest tenth: x² + x - 5 = 0.
Anestetic [448]

Answer:

Step-by-step explanation:

We can use the quadratic formula to get the answer to this

Quadratic Formula: -b +- √b² - 4ac/2a

Once we input A, B, and C into this, and solve any multiplication, we get

x = -1  +- √1 + 20/2

We divide by 2a, which 2a = 2.

-0.5 +- 10.5.

these are the following values of x:

x = 10

x = 11

Pretty sure this is it, hope it helps!

Helpppppppp plz I'm not rlly good at area
Nitella [24]
For number 8, the area will be 350 square yard because the total area of the rectangle is 20 times 18 will equal 360 square yards, and I know that the area of the cutting rectangle is 5 times 2 equals 10 square yard, so the rest of the rectangle will be 360-10 or 350 square yards. For number 9, the area will be 28 square meters because the area of the whole rectangle is 40 square meters, and I found the area of the rectangle that already cut which equal 4 times 3 equal 12 square meters, so the area of the rectangle that does not cut will be 40-12 or 28 square meters. For number 10, the answer will be 92 square feet because the area of the complete rectangle wipp be 14 times 10 equal 140 square feet, and the area of the rectangle that already cut is 8 timed 6 equal 48 square feet, so the area that had left will equal 140-48 or 92 square feet. Hope it help!

Help with this math question please

| -6x - 3 | > 15

This expression can be written as:

a) -6x - 3 > 15 
b) -15 > - 6x - 3

Solving a part:

- 6x - 3 \ \textgreater \  15 \\  \\ 
- 6x \ \textgreater \  18 \\  \\ 
x \ \textless \  -3

Solving b part:

-15 \ \textgreater \  - 6x - 3 \\  \\ 
-12 \ \textgreater \  - 6x \\  \\ 
2 \ \textless \  x

or we can write:
x > 2

So the solution to given inequality is:
x \ \textless \  -3  \\ or  \\ x \ \textgreater \  2

The second option correctly lists this solution.
