Answer:

204 cm

Step-by-step explanation:

Triangle area = base × height ÷ 2

6×4÷2=12

Rectangle area = side 1 × side 2

6×10=60

5×10=50

There are 2 triangles, so make 12×2=24, 24 is the surface area of the triangles.

There are 2 rectangles with 5 in one side, so make 50×2=100 of area of this 2 rectangles

Now just sum the areas:

100+24+60= 204

If six more than the product of a number and -2 is greater than 10, which of the following could be that number

laiz [17]

To get that number in the problem, you need to translate first the word problem into mathematical expression.

We will let x as the number.
six more than the product of a number and -2 is greater than 10 can be written as (-2x) + 6 > 10
We will now solve for x to get the number.
   (-2x) + 6 > 10
Add -6 to both sides of the equation
      -2x + 6 - 6 > 10 - 6
      -2x > 4
Divide both sides of the equation with -2
Take note that if we divide a negative number in inequality, the inequality symbol will be change from greater than to less or from less than to greater than.
   -2x / -2< 4 / -2
   x < -2

Therefore, the number that we are looking for is less than -2.
