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: 1
Step-by-step explanation:
-11, -7, -3...
you add 4 each time so the next number would be 1
I believe it is corresponding to the value of x in type of situational problem.
