Area of the rectangle is 2*6=12 in^2
12 could be = 1*12  or 2*6   or 3*4 
P could be 2*(1+12)=2*13=26 
                  2*(2+6)=2*8=16
                   2*(3+4)=2*7=14

the answer is 24 in  (c)

Select TWO equations that represent angle relationships in the figure. A 7x−9=6x+14 B 7x−9=5x−10+33 C 6x+14=33+180−(7x−9) D 33+(

The value of x from the figure is 1 and the equations that represent angle relationships in the figure are 7x + 5x = 3 + 9 and 12x = 12

<h3>Lines and angles</h3>

The point where two lines meet is known as an angle. From the given diagram;

7x-9 = 5x + 3

Determine the value of x

7x + 5x = 3 + 9
12x = 12
x = 12/12

x = 1

Hence the value of x from the figure is 1 and the equations that represent angle relationships in the figure are 7x + 5x = 3 + 9 and 12x = 12

What is the value of x
pashok25 [27]

Answer:

-10

Step-by-step explanation:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result. Therefore, the value of x is -10.

Please help me with this. I think I understand it and know what it is but I just want someone to check it for me to see if I'm r

Ok, so
Length = L
Width = L + 7

Since area = length x width, then

30 = L × (L + 7)

Remember that L + 7 Is width so...

L + 7 = 30/L

So the expression for the width in terms of length would be...
w = 30/L - 7
