Answer:
3 inches
Step-by-step explanation:
(14+2x) × (15+2x) = 2(14×15)
210 +30x +28x + 4x² = 420
4x² + 58x - 210 = 0
2x² + 29x - 105 = 0
2x² + 35x - 6x - 105 = 0
x(2x + 35) - 3(2x + 35) = 0
(x - 3)(2x + 35) = 0
x = 3, -35/2(not possible)
The answer is: x = 2 ∨ x = -1
f(x) is a linear function with no restrictions
Domain: x = All real numbers
Range: y = All real numbers
21 times x to the fifth (where x is the ratio between values) equals 1240029
1240029/21=59049
59049^(1/5)=9
so the values are 21, 21*9, 21*9^2, 21*9^3, 21*9^4, 1240029
the sum of these values is 1395030
Rules for SN = must be a number from 1 and less than 10 times a power of 10
So our number becomes
2.22 x 10⁸ - It takes a move of 8 places to the right to make the number 222,000,000
