Answer:
Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as
where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40
substitute
apply distributive property
see the attached figure to better understand the problem
Step-by-step explanation:
we can find the length of other side by hypotenuse formula,
which is h² = a² + b²
so,
a = 157
b = 168
now after inserting the values we got,
→ h² = (157)² + (168)²
→ h = 24649 + 28224
→ h = 52,873
→ h² = √52873 = 229.94
so, length of other side is 229.94

Answer:
- first rectangle: 18 by 9
- second rectangle 21 by 6
- x = 9
Step-by-step explanation:
The perimeter in each case is double the sum of the side dimensions. Since the perimeters are equal, the sum of side dimensions will be equal:
2x +x = (x +12) +(x -3)
3x = 2x +9 . . . . . . . . collect terms
x = 9 . . . . . . . . . . . . . subtract 2x
Given this value of x, the dimensions of the first rectangle are ...
{2x, x} = {2·9, 9} = {18, 9}
And the dimensions of the second rectangle are ...
{x+12, x-3} = {9+12, 9-3} = {21, 6}
