Question

Can any body tell me the last 2 answers please the last box and the cicle next to it

Answer 1

Answer:

Step-by-step explanation:

2nd row:

Answer = 4x + 3y + 2x - y    {Write the like terms together}

            = 4x + 2x + 3y -y

            = 6x + 2y

3rd row:

Unknown value + (x + 4y ) = 4x + 5y

Unknown value = 4x + 5y - (x + 4y)  

                          = 4x + 5y -x - 4y               {Write the like terms together}

                          = 4x - x + 5y - 4y

                          = 3x + y

 

Answer 2

Answer:

2nd row, circle is 6x + 2y.

3rd row, rectangle is 3x + y and circle is 5x.

Step-by-step explanation:

As the question say when 2 rectangles, at the sides are add up together, it will form circle in the middle. So in order to find circle or rectangle, you either have to add or substract :

For 2nd row, circle,

T/L(r) + B/R(r) = M(c)

4x + 3y + 2x - y = M(c)

6x + 2y = M(c)

M(c) = 6x + 2y

For 3rd row, rectangle,

T/L(r) + B/R(r) = M(c)

x + 4y + B(r) = 4x + 5y

B(r) = 4x + 5y - x - 4y

= 3x + y

For 3rd row, circle,

T/L(r) + B/R(r) = M(c)

2x - y + 3x + y = M(c)

5x = M(c)

M(c) = 5x

* Take note, for 3rd row, you first have to find the rectangle then circle.

Symbols :

• T/L(r) = Top/Left (rectangle)
• B/R(r) = Bottom/Right (rectangle)
• M(c) = Middle (circle)
