Expand the expression 3(7 + x)
Gre4nikov [31]

Answer:

3x + 21 or 21 + 3x

Step-by-step explanation:

Remark

This is an example of the distributive property. Of all the fundamental rules used in solving equations, this is likely the most important, at least at beginning levels.

Solution

What this is saying is two things.

1. you must multiply both terms on either side of the + sign by the factor outside the brackets.

2. You must not destroy a plus (or minus) sign unless the two terms inside the brackets are exactly the same.

3(7 + x)           The terms are not the same, so your answer must have a plus sign

Left side of the plus: 3*7

Right side of the plus: 3 * x

The answer then is 21 + 3x

It is more commonly written as 3x + 21

A trapezoid has base lengths of 12 centimeters and 13 centimeters. The other sides have lengths of 5 centimeters and 10 centimet
r-ruslan [8.4K]

Answer:

The area of the composite figure is 392.12cm^{2}.

Step-by-step explanation:

The area of the composite figure = area of trapezoid + area of rectangle

Area of trapezium = \frac{1}{2} ( a +b)h

Where: a is the length of the first base, b the length of the second base and h is the height of the trapzium.

Applying Pythagoras theorem, the height, h, is;

h = \sqrt{5^{2} - 1^{2}  }

  = \sqrt{24}

h  = 2\sqrt{6}

Area of trapezium = \frac{1}{2} ( a +b)h

                              = \frac{1}{2} (13 + 12) × 2\sqrt{6}

                              = 156\sqrt{6}

                              = 382.12cm^{2}

Area of trapezium is 382.12cm^{2}

Area of rectangle = length × width

                             = 5 × 2

                             = 10 cm^{2}

Area of rectangle = 10 cm^{2}

Therefore,

area of the composite figure = 382.12 + 10

                                               = 392.12cm^{2}
