Answer:
30.48 cm
Step-by-step explanation:
There are ~ 2.54 centimeters in 1 inch. If the ruler is 12 inches long, multiply 2.54 cm by 12:
12 inches x 2.54 cm = 30.48 cm.
I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3
x=4
y=-3
(4,-3)

Answer:
(x + 2)²
Step-by-step explanation:

a² = 4 ⇒ a = 
= 2, thus
x² + 4x + 4 = (x + 2)²
