Answer:

Value of A = 10

Step-by-step explanation:

Here Isoke is solving the quadratic equation by completing the square

        10x² + 40x – 13 = 0

         10x² + 40x – 13 + 13 = 0 + 13

         10x² + 40x + 0 = 13

         10x² + 40x = 13

          10 ( x² + 4x) = 13

   Here it is given as

           A(x² + 4x) = 13  

Comparing both

           We will get A = 10

Value of A = 10

The edge of each cube used to build this rectangular prism is 13
kolbaska11 [484]

Answer:

\frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3

====================================================

Step-by-step explanation:

The question is missing the attached figure.

The edge of each cube used to build this rectangular prism is 1/3 inch long. Based on the attached figure.

the volume of the prism = length × height × width

length = 3 * \frac{1}{3} = \frac{3}{3}

height = 3 * \frac{1}{3} = \frac{3}{3}

width = 2 * \frac{1}{3}= \frac{2}{3}

So the volume of the prism = \frac{3}{3} *\frac{3}{3} *\frac{2}{3} =\frac{2}{3} \  in^{3}

∴ The equation that shows the volume of the prism, in cubic inches

= \frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3

Segments AB, DC and Ec intersect at point C. Angel DCE measures 148. Find the value of x.
Anna71 [15]

The image is attached.

Answer:

x = 16°

Step-by-step explanation:

Segment AB, segment DC and segment EC all intersect at point C.

Here, we are told angle DCE measures 148°.

This is a semi-circle, and the total angle of a semi-circle is 180°.

Which means, x+x+148 = 180

Solving for x, we have:

x+x+148 = 180

2x + 148 = 180

2x = 180 - 148

2x = 32

x = \frac{32}{2}

x = 16°

The value of x is 16°
