Answer:

n=5

Step-by-step explanation:

7n-4=31

The goal is to get the variable alone. Start by adding 4 to both sides.

7n=35

To separate the n further we divide both sides by 7.

n=5

We can actually plug that value in to check our answer.

7×5-4   this value does equal 31, so we know it is correct.

HELP PLEASE!!!!
mina [271]

Answer:


Step-by-step explanation:

1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7

2)Subtract 7 from both sides

4x+7=39

-7       -7

4x=32

3) Divide by 8

x=8

Thus we get x=8 as answer

So reasons are

i) Distributive property

ii) Subtraction property of equality

iii) Division property of equality

For the rectangle: l x w = Area
l = 18
w = 18

18 x 18 = 324

If 16m is for dash line

1/2bh
1/2(16)(16)
4(16) = 64

1/2bh
1/2(8)16
8(8) = 64

324 + 64 + 64 = 452

Your area should be 452m²

hope this helps
