The floor of a rectangular cage has a length 4 feet greater than its width, w. James
guajiro [1.7K]

Answer:

x² + 8x + 12

Step-by-step explanation:

Area of a rectangle = length × width

Original dimensions:

Width = x

Length = x + 4

James will increase both dimensions of the floor by 2 feet

New dimensions:

Width = x + 2

Length = x + 4 + 2

= x + 6

Area of the new rectangle = length × width

= (x + 2) × (x + 6)

= x² + 6x + 2x + 12

= x² + 8x + 12

Equation which represents the

new area, N, of the floor of the cage = x² + 8x + 12

The graph shows a system of equations:
Leviafan [203]

Answer:

c. (3, 2)

Step-by-step explanation:

Equating the values of y :

  • -x + 5 = x - 1
  • x + x = 5 + 1
  • 2x = 6
  • <u>x = 3</u> [x-coordinate of the solution]

Finding y by substituting x in one of the equations :

  • y = x - 1
  • y = 3 - 1
  • <u>y = 2</u> [y-coordinate of the solution]

Solving :

  • Solution = (x, y)
  • Solution = (3, 2)

Which form of a quadratic function is easiest to use when finding the maximum or minimum value of the function?
alexandr402 [8]

Answer:

ax² + bx + c

Step-by-step explanation:

The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.

Suppose a quadratic function:

f(x) = 2x² - 8x + 9

Use ( -b/2a ,  f(-b/2a) ).

-b/2a

a = 2

b = -8

-(-8)/2(2)

8/4

= 2

f(2) = 2(2)² - 8(2) + 9

f(2) = 2(4) - 8(2) + 9

f(2) = 8 - 16 + 9

f(2) = 1

The minimum value of this quadratic function is (2, 1).

It represents a minimum value because a > 0.

Using the digits 0 to 9 ​
Gre4nikov [31]

Supplementary Angles:

\boxed{100°} and \boxed{80°}

Arithmetically speaking, the closest 2 supplementary angles can get (in 3 and 2 digits respectively) is the upwritten.

Complementary Angles:

\boxed{45°} and \boxed{45°}

Simply, in this case, for angles to be numerically as close as possible - make both the angles 45°.
