In order to combine like terms, they have to first be organized. First combine the terms with the variable x, then the terms with no variables.

3x+13.5+5.2x-6
3x+5.2x=8.2x
13.5-6=7.5

The final simplified expression is 8.2x+7.5.

The perimeter of a rectangle is 42 cm. The width is 7 cm less than the length.
lara [203]

Answer:

<h2>Length = 14</h2><h2>Width =7</h2>

Step-by-step explanation:

Let \:the\:length\:be \:x\\Perimeter = 42 cm\\Width = x -7\\\\P = 2(l+b)\\\\42 = 2(x+(x-7))\\\\42 = 2(x +x-7)\\42 = 2(2x-7)\\42 = 4x -14\\Collect\:like\:terms\\\\42+14=4x\\56 = 4x\\\\Divide \:both\:sides\:of\:the\:equation\:by \:4\\\frac{56}{4} = \frac{4x}{4} \\\\14 =x\\Length = 14\\Width = x-7\\Width = 14-7\\\\Width = 7

A football player ran the ball for 40 yards, 45 yards, 48 yards, 52 yards, and 105 yards. What is the outlier?
Vinil7 [7]
An outlier is a value that is much higher or much lower than the rest of the values in the data set.

The answer here is 105 because it is nearly double all other values.
65 is incorrect because it's not even a value in the data set.

Find the
Mazyrski [523]

Answer:

54 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is

A = \frac{s^2\sqrt{3} }{4}  ( s is the side length ) then

\frac{s^2\sqrt{3} }{4} = 81\sqrt{3} ( multiply both sides by 4 to clear the fraction )

s²\sqrt{3} = 324\sqrt{3} ( divide both sides by \sqrt{3} )

s² = 324 ( take the square root of both sides )

s = \sqrt{324} = 18

Thus

perimeter = 3 × 18 = 54 cm
