Marisol is panting on a piece of canvas that has an area of 180 square inches the length of the painting is 1 and 1 fourth times
NeTakaya

Answer: Length = 15 inches

Width = 12 inches

Step-by-step explanation:

The painting is rectangular.

Let L represent the length of the painting.

Let W represent the width of the painting.

Area of a rectangle = LW

Marisol is panting on a piece of canvas that has an area of 180 square inches. It means that

LW = 180- - - - - - - - - - -1

The length of the painting is 1 and 1 fourth times the width. It means that

L = 1.25W

Substituting L = 1.25W into equation 1, it becomes

W(1.25W) = 180

1.25W² = 180

W² = 180/1.25

W² = 144

W = √144

W = 12 inches

L = 1.25W = 1.25 × 12

L = 15 inches

iren [92.7K]

Answer:

4

Step-by-step explanation:

Simplify x and y by rationalising the denominator of both

To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of 2 + \sqrt{3} is 2 - \sqrt{3}

The conjugate of 2 - \sqrt{3} is 2 + \sqrt{3}

x = \frac{1(2-\sqrt{3)} }{(2+\sqrt{3})(2-\sqrt{3})  } = \frac{2-\sqrt{3} }{4-3} = 2 - \sqrt{3}

y = \frac{1(2+\sqrt{3}) }{(2-\sqrt{3})(2+\sqrt{3})  } = \frac{2+\sqrt{3} }{4-3} = 2 + \sqrt{3}

Thus

x + y = 2 - \sqrt{3} + 2 + \sqrt{3} = 4
