We can set up the width a X and, from the description the length would be 3X-1. The perimeter of a rectangle is determined by 2XL + 2Xw. Plugging into the equation 2(3X-1) + 2(X) = 118. Next distribute to get 6X-2 + 2X = 118. Combine like terms to get 8X = 120. Divide by 8 to get X = 15. The width is 15. The length is 3(15)-1 or 44. 88 +30 = 118
Hello,
x² + 5x + 6 = 0
a = 1 ; b = 5 ; c = 6
∆ = b² - 4ac = 5² - 4 × 1 × 6 = 25 - 24 = 1 > 0

Step-by-step explanation:
Answer:
compound interest would be,
1495.91
and simple interest would be,
1470
Step-by-step explanation:
compound interest would look like,
1200 x 1.045 x 1.045 x 1.045 x 1.045 x 1.045
and simple interest would look like,
1200 x 0.045 = 54 = 4.5%
54 x 5 = 270
1200 + 270 = 1470
