Answer:
The equation that best represent the situation is;
x^2 = 576
or x^2 -576 = 0
Step-by-step explanation:
Here, we want an equation that best represent the given information in the question.
The length of the garden is twice as long as it is wide
So, given that x is the length of the garden, then x/2 will represent the width of the garden
From the description given in the question, the garden would be rectangular in shape.
Mathematically, the area of a rectangle can be calculated using the formula;
L * B = area
Thus;
x * x/2 = 288
x*2 = 2 * 288
x^2 = 576
Answer:
$20.96
Step-by-step explanation: 6.45 times three equals 19.35 plus a quarter of 6.45 equals 1.6125 which you round to 1.61. So 19.35+1.61= 20.96
Answer:
x=4
Step-by-step explanation:
5(x-10) = 30- 15x
5x - 50= 30 - 15x
+15x +15x
20x - 50 = 30
+50 +50
20x = 80
/20 /20
x = 4
Hope this helps!
Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2
