1. What property allows the expression 4.7x + 10.4 + 15.3x − 8.4x + 15.6 to be simplified to the equivalent expression 20x + 10.
Elis [28]

Answer:

  • commutative property
  • distributive property

Step-by-step explanation:

The expression

  4.7x + 10.4 + 15.3x − 8.4x + 15.6

can be simplified in a few stages. First of all, we use the commutative property of addition to swap terms 2 and 3.

  4.7x +15.3x +10.4 -8.4x +15.6

Next, we use the distributive property to factor x from the first two terms.

  (4.7 +15.3)x +10.4 -8.4x +15.6

Now we perform addition.

  20x +10.4 -8.4x +15.6 . . . . . . . . equivalent expression

A rectangle with a length of L and a width of W has a diagonal of 10 inches. Express the perimeter P of the rectangle as a funct
KatRina [158]
<h2>Answer:</h2>

The expression which represents the perimeter P of the rectangle as a function of L is:

          Perimeter=2(L+\sqrt{100-L^2})

<h2>Step-by-step explanation:</h2>

The length and width of a rectangle are denoted by L and W respectively.

Also the diagonal of a rectangle is: 10 inches.

We know that the diagonal of a rectangle in terms of L and W are given by:

10=\sqrt{L^2+W^2}

( Since, the diagonal of a rectangle act as a hypotenuse of the right angled triangle and we use the Pythagorean Theorem )

Hence, we have:

10^2=L^2+W^2\\\\i.e.\\\\W^2=100-L^2\\\\W=\pm \sqrt{100-L^2}

But we know that width can't be negative. It has to be greater than 0.

Hence, we have:

W=\sqrt{100-L^2}

Now, we know that the Perimeter of a rectangle is given by:

Perimeter=2(L+W)

Here we have:

Perimeter=2(L+\sqrt{100-L^2})
