1 answer:
Answer:
76
Step-by-step explanation:
Survey response
Those who liked the proposed plan=380 persons
Those who didn't like the proposed plan=120 persons
We assume that the these are the only people who participated, with those who never took sides being zero
Total number of people surveyed=380 persons+120 persons=500 persons
Percentage of those who liked =
Therefore, the percentage that liked the plan is 76%

Answer:
8
Step-by-step explanation:
f(x) = (x+2)(x-2)
Substituting x=1 into f(x):
f(1) = 3*-1
= -3
Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.
Hence,
3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8
This can be confirmed with a graph, as attached below.

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
