Answer:

10x²+11-2x

Step-by-step explanation:

I hope you mean 7x²+8+5, not 7x²+8x+5.

We need to combine like terms. Anything with squared should be added together, et cetera.

(7x²+8+5)+(3x²-2x-2)

You can take out the parenthesis, because they don't matter in addition.

7x²+8+5+3x²-2x-2

Add the terms, step by step. Each bold pair needs to be added together.

7x²+8+5+3x²-2x-2

10x²+8+5-2x-2

10x²+11-2x

Now there's no more we can add together.

Find the perimeter and the area of the figure. A right-angled trapezoid has a shorter base of 7 centimeters, longer base of 9.5

laila [671]

The given dimensions of 9.5, 6, 7, and 6.5 cm gives the following

perimeter and area of the trapezium.

Perimeter: <u>29 cm</u>

Area: <u>49.5 cm²</u>

<h3>How can the area and perimeter of the trapezium be found?</h3>

The perimeter of a trapezoid is given as follows;

Perimeter = The sum of the lengths of the sides

Which gives;

Perimeter = 6 + 7 + 6.5 + 9.5 = 29

The perimeter of the trapezoid =<u> 29 cm</u>

Perimeter: 29 cm

The area of the trapezoid is given as follows;

$Area = \mathbf{ \dfrac{Sum \ of \ the \ parallel \ sides }{2} \times Height}$

Which gives;

$Area = \dfrac{7 + 9.5 }{2} \times 6 = 49.5$

The area of the trapezoid = 49.5 cm²

Area:<u> 49.5 cm²</u>

Which fraction is equal to 5/6? 8/22, 25/30, 5/15?

nadya68 [22]

If the fraction cannot be simplified any more, you can multiply both the numerator and denominator by an number.

5/6 (multiply the top and bottom by 2) is the same as 10/12
8/22 (can be simplified by dividing top and bottom by 2) is 4/11
25/30 (simplified by dividing by 5) is 5/6
5/15 (simplified by dividing by 5) is 1/3

Hope this helps!
