Answer:
C. 40 cm
Step-by-step explanation:
length of side of square = s
perimeter = s + s + s + s = 4s
We use the formula P = 4s
P = 4 * 10 cm
P = 40 cm
Answer: The perimeter is 40 cm.
Notice that the perimeter is a sum of lengths, so its units are linear units such as cm, inches, feet, a unit of length.
An area has square units such as cm^2, in.^2, ft^2, etc.
Answer:
Let's solve for x.
4x+2y=5
Step 1: Add -2y to both sides.
4x+2y+−2y=5+−2y
4x=−2y+5
Step 2: Divide both sides by 4.
4x

Let's solve for x.
−4x−5y=7
Step 1: Add 5y to both sides.
−4x−5y+5y=7+5y
−4x=5y+7
Step 2: Divide both sides by -4.
−4x
