The side length of the square is 2*((8/2)^.5) = 4cm
The area is 4^2 = 16 cm

See the attached picture. The parts labeled a and b are both the same length since this is a square. And each of them is half of the side length of the square. We can find the length of a and b using the Pythagorean theorem because the 8cm is a hypotenuse of a right triangle. So we find a, and multiply by 2 to get the square side length. Then we square that to get the square area.

Solve the inequality for x. –4x + 6 < 50 A) x > –11 B) x > –14 C) x < –11 D) x < –14
Natali [406]

Answer:

x > -11

Step-by-step explanation:

<u>Step 1:  Subtract 6 from both sides</u>

-4x + 6 - 6 < 50 - 6

-4x < 44

<u>Step 2:  Divide both sides by -4</u>

-4x / -4 < 44 / -4

If you divide by a negative number, you flip the sign.

<em>x > -11</em>

Answer:  x > -11

Find the area of the figure
lana [24]

Answer:

Below

Step-by-step explanation:

First I found the area of the portion that extends off (if that makes sense??)

It is a triangle, so use A = bh/2

A = (2)(6) / 2

   = 6 cm^2

Next I found the area of the rectangle using A = LW

A = (6)(3)

   = 18 cm^2

Total area = 18 + 6

                 = 24 cm^2

Hope this helps! Best of luck <3
