Answer:
<u>1.16 m (approximately)</u>
Step-by-step explanation:
Let x be the width of the path.
Total area = (5+2x)(3+2x) = 39
Expand and simplify
4x²+ 16x+15-39 = 0
4x² + 16x - 24 = 0
Simplify
x² + 4x -6 = 0
Rational factoring does not work, so use quadratic formula
x = +/- sqrt(10) -2
= 1.16 or -5.16 (reject)
= <u>1.16 m (approximately)</u>
Answer:
10 inches by 7 inches
Step-by-step explanation:
Let L and W represent the length and width of the rectangle, in inches. Then L = W + 3.
The perimeter is P = 2L + 2W, or P = 2(W+3) + 2W = 34 inches.
Solving for W: 2W + 6 + 2W = 34 inches, or
4W + 6 = 34 inches, or
4W = 28 inches, or W = 7 inches.
Given that L = W + 3, L = (7 inches) + 3 inches = 10 inches.
The length of the rectangle is 10 inches, and its width is 7 inches.
Answer:
Step-by-step explanation:
For the first few exponents multiply and the rest they add because like terms.
The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.
