The perimeter is the total outside dimensions.
There are 2 sides that are 8 inches and 2 sides that are 5 inches.
Perimeter = 8+8+5+5 = 26 inches.
1. <APC = <DQB [ Given]
2. Arc(AC = BD) [ Equal angles subtend equal arcs]
3. AB//CD [From 2]
Answer:
A = (q + z / 2)m
Step-by-step explanation:
9 + z / 2 . m =A
(q + z)m / 2 = A
(q + z)m/2 / m = A / m
2(q + z / 2) = 2(a / m)
Simplify Left:
q + z = 2(a / m)
Simplify right:
q + z = 2A / m
Subtract z from both sides
q = 2A / m -z
A = (q + z / 2)m
The answer is 440.
24 * 10 = 240
10 * 20 = 200
240 +200 = 440
The appropriate choice is ...
... On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.
_____
Had Brianna simplified her effort properly on line 4, she would have
... -0.1 +0.1x = -1.4
putting her essentially back where she started—with a 2-step equation.
