Brian is adding the lengths of wood posts that he has left from building a pen for his chickens. A photo of chickens is shown.

The lengths are 323, 214, and 213. Brian began with 20 feet of wood.

Write and then evaluate a fraction expression to determine how much wood he used for the pen.
Enter the correct expression in the box.

2 of 2
Simplify inside the parentheses, and then subtract.

Expression: $$

He used
feet.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

hope this !

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75

all of them are elements inside set of real numbers since none of them appears to have complex number form.

hope this .
