Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2. The equation is true for these two x-values.

Carla wants the total weight of the bags to be four pounds. If she can only pick one more bag, which bag weight should she pick?

pychu [463]

Answer:

1/8

Step-by-step explanation:

To find which bag weight Carla needs, the first step is to find the total weight of the bags shown in the line plot.

There are three -pound bags.

There are six -pound bags.

There are four -pound bags.

Multiply the weight and number of each bag to find the total weight of each different weight bag.

Now, add the three totals.

Finally, subtract the total weight from four pounds in order to find which weight Carla needs.

So, Carla should pick one -pound bag of candy to total four pounds.

Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyra

mina [271]

Answer:

Akira needs 45 square inches of gold foil to cover the chair free including the bottom

Step-by-step explanation:

Total surface = surface area of the base square + area of 4 triangles

Step 1: The surface area of the base square

surface area of the base = surface area of the square = $s^2$

where s is the side length

The the surface area of the base = $3^2$ = 9 square inches

Step 2: The surface area of the side triangles 

The area of the triangle = $\frac{1}{2}\times \text{side length} \times \text{slant height}$

On substituting the values,

The area of the triangle = $\frac{1}{2} \times 3 \times 6$

The area of the triangle = $\frac{18}{2}$

The area of the triangle = 9 square inches

Now the area of 4 triangles = 4 x 9 = 36 square inches

Thus the total surface area = 9 + 36 = 45 square inches
