Answer:
i.
+ 26x + 144 - 299 = 0
ii. x = 5
Step-by-step explanation:
The area of the figure = 299 cm²
The figure has a shape of a rectangle, so that;
Area of rectangle = length x width
length of the figure = 18 + x
width of the figure = 8 + x
Area of the figure = (18 + x) x (8 + x)
299 = (18 + x) x (8 + x)
299 =
+ 26x + 144
+ 26x + 144 - 299 = 0
+ 26x - 155 = 0
applying the trigonometric formula;
x = (-b ±
) ÷ 2a
= (-26 ±
) ÷ 2
= (-26 ±
) ÷ 2
= (-26 ±
) ÷ 2
= (-26 ± 36) ÷ 2
x = (-26 + 36) ÷ 2 OR x = (-26 -36) ÷ 2
= 10 ÷ 2 OR -62 ÷ 2
= 5 OR -31
Thus, x = 5
Answer:
0.5 inch on the drawing
Step-by-step explanation:
The following information is missing:
<em>The scale factor of the drawing to the actual flag is represented by the ratio 1:18. </em>
This scale factor means that 1 inch on the drawing are equivalent to 18 inches o
n the actual flag. We want to know the height on the drawing, given that a height of 9 inches is drawn on the actual flag. The following proportion must be satisfied:
1 inch on the drawing / x inch on the drawing = 18 inches o
n the actual flag / 9 inches o
n the actual flag
x = 9/18 = 0.5 inch on the drawing
