Answer:

4. 9h + 6x + 3

5. 10y - 3

Step-by-step explanation:

Figure 4

Perimeter

= 4h + 6 + 2x + 5h + 4x - 3

= 9h + 6x + 3

Figure 5

Perimeter

= 3y - 2 + 2y + 2 + 2y - 2 + y + 2y - 1

= 10y - 3

How can you solve n-6m=8 for n

disa [49]

To solve for n you have to get n on one side of the equation by itself.
n-6m=8
take -6m and add to both sides. so the side that has n evens out to 0. then you have
n=6m+8
it is this way because you can only add like terms. This should be all you need to do.
Hope this helps

The midpoint of AB is M(3,-1).If the coordinates of A are (8,4) what are the coordinates of B

Alchen [17]

Answer:

B(-2,-6)

Step-by-step explanation:

The midpoint of AB is M, then A(8,4), M(3,-1)

So we can find:

$x_{B} =2x_{M} -x_{A}= 2*3-8= -2\\y_{B}= 2y_{M} -y_{A} = 2*(-1)- 4= -6\\$

then B(-2,-6), hope that useful.
