Answer:

Step-by-step explanation:

okay, so here are a few methods you can use.

___

1) +

x + 7 = 10 so because this is addition we use the reverse, subtraction. So

x - 7 = 10 - 7 and that equals to 3.

2) -

x - 2 = 10 so because this is subtraction we do the reverse, addition.

x + 2 = 10 + 2 and that equals to 12.

3) x

x times 3 = 21 because this is multiplying we divide.

x/3 = 21/3 and that would be 7.

4) /

x/2 = 10 same as above, reverse is multiplying.

x times 2 = 10 times 2 and thats 20.

The area of the rectangle will be 150 square meters.

<h3>What is an area?</h3>

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that:-

  • The length of a rectangle is 5 m longer than its width.
  • The perimeter of the rectangle is 50 m.

The area will be calculated as follows:-

From the given condition in the question, we can form two linear equations they are:-

The length of a rectangle is 5 m longer than its width.

L = w + 5

L - w = 5

The perimeter of the rectangle is 50 m.

P = 2 (L + w )

2 ( L+ w ) = 50

L + w = 25

by solving the two equations we will get the values of L and w.

L - w = 5  or w = L - 5

L + w = 25

L + L - 5 = 25

2L = 30

L = 30 / 2

L = 15

Put the value of L in any equation to get w.

L - w = 5

15 - w = 5

w = 10

Now the area of the rectangle will be:-

A = L x w

A = 15 x 5

A = 150 square meters.

Therefore the area of the rectangle will be 150 square meters.

To know more about an area follow

9 and 11 need help<br> Mark brainlist
zvonat [6]

I will do 9 only. You can do 11.

Question 9

sin(60) = x/8

sin(60)(8) = x

4•sqrt{3} = x

x^2 + y^2 = 8^2

(4•sqrt{3})^2 + y^2 = 64

16(3) + y^2 = 64

48 + y^2 = 64

y^2 = 64 - 48

y^2 = 16

sqrt{y^2} = sqrt{16}

y = 4

Do 11 the same way.
