PART A

Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box

PART B

Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.

The diagram shows a prism.

<h3>Correct Response;</h3>
  • <u>The drawing of the front and side elevation is attached</u>;
<h3 /><h3>Construction Method used to Draw the Required Elevation</h3>

The given scale = 2 squares to 1 m

Number of squares in the plane on which the front elevation is to be drawn = 16 squares

<h3>Front elevation;</h3>

The number of squares in the width of the front elevation = 4 squares

The number of squares in the front part closest to the observer = 4 × 1 squares

Number of squares in the slant surface of the = 3 squares by 4 squares

  • <u>Please find attached the drawing of the </u><u>front elevation</u><u> of the given </u><u>diagram</u>.

<h3>Side elevation;</h3>

Using the same pattern as above, we have that the side elevation is given as follows;

The width of the lower side of the side elevation = 2 meters = 4 squares

The height of the side elevation = 2 meters = 4 squares

  • <u>Please find attached the drawing of the required front and side elevation</u>;

Which zero pair could be add into the function f(x)=x^2+12x+6 so that the function can be written in vertex form
Ilia_Sergeevich [38]

We need a perfect square, and we start with


x^2+12x


This means that the binomial begins with (x+\ldots)^2, and 12x is the double product of x and the number we're looking for. So, that number is 6. Since


(x-6)^2 = x^2-12x+36


we need to add 30 (and subtract it to leave the expression untouched. So, we have


x^2-12x+6 = x^2-12x+6 + 30 - 30 = (x-6)^2 - 30
