How do you solve this? [question in attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

In order to find the perimeter of a shape, we should add all of its sides.

Since a triangle has only 3 sides, we add 3 sides together, like so:-

      ⇒ 9x-7+12x-13+3x+8

Combine like terms:-

    ➪ 9x+12x+3x-7-13-8

Which simplifies to

     ➪9x+15x-7-21

On further simplification,

➪24x-28

So we conclude that the perimeter of the triangle is 24x-28 units.

Joseph saved his money to buy your table computer he purchased a computer with those cuz she had he gave the sale clark 4 hundre

Hello! We know that we have $400. So 23 ten dollar bills is equal to $230. How? We multiply 23 x 10 and get $230. Then, we have 46 dimes. A dime is worth 10 cents so we multiply 46 x 10 which equals $4.60. And of course we have the 19 cents. Now we add. 400 + 230 + 4.60 + 19 = $653.6.

Hope this Helps!

Find the area of the shape shown below.
vlabodo [156]

Answer:

6cm^{2} (assuming the units is in centimetres)

Step-by-step explanation:

Hi, hope this helps!

Method 1:

Calculate this shape as a trapezium. This is a trapezium because it has one pair of parallel sides. The way to calculate the area of a trapezium is this:

- Half the sum of the parallel sides

- Multiply the perpendicular height between them

In this case, 4 and 2 are parallel, so we add them together (4 + 2 = 6) then we divide by two (6 ÷ 2 = 3). Then we multiply our answer by the perpendicular length between the two parallel sides (assuming the side on the left is at a right-angle, 3 x 2 = 6).

Method 2:

Calculate this shape as a rectangle + a triangle. If you split the shape so the pointy bit on the right becomes a triangle and the left becomes a square, you can calculate the area without knowing the formula for calculating a trapezium (see above ^).

- Area of the square / rectangle = length x width = 2 x 2 = 4

- Area of the triangle = 1/2 x length x width = 2 x 2 x 1/2 = 4 x 1/2 = 4 ÷ 2 = 2

Then we add the two areas together (4 + 2 = 6).

I hope this helped and I wasn't waffling on :)
