Answer:
x=2 meters
Step-by-step explanation:
length = 12+2x
width = 6+2x
Area = (12+2x) (6+2x) = 160
Foil
72 + 12x+24x+4x^2 = 160
Combine like terms
4x^2 + 36x +72 = 160
Subtract 160 from each side
4x^2 +36x -88 =0
Divide by 4
x^2 +9x -22=0
Factor
What 2 numbers multiply to -22 and add to 9
11 * -2 = -22
11+ -2 = 9
(x +11) (x-2) =0
Using the zero product property
x=-11 x=2
Since we cant have negative length
x=2
Answer:
12
Step-by-step explanation:
Answer:
it definitely has eight sides so I'm not completely sure but try Nonagon (9 sides) and heptagon (7 sides) Just in case if not I think maths watch is bugged as it does that sometimes <3
Answer:
First, find the common difference for the sequence. Subtract the first term from the second term. Subtract the second term from the third term. Subtract the third term from the fourth term. To find the next value, add to the last given number.
Step-by-step explanation:
Answer:
Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 64
Step-by-step explanation:
<u>Information</u>
Domain: set of all possible input values (x-values)
Range: set of all possible output values (y-values)
From inspection of the diagram, the minimum value of x is 0 and the maximum value of x is 4.
Therefore, the domain is: 0 ≤ x ≤ 4
From inspection of the diagram, the minimum value of y is 0 and the maximum value of y is 64.
Therefore, the range is: 0 ≤ y ≤ 64
