Step-by-step explanation:
Answer:
(D) (a + 4)/2
Step-by-step explanation:
To solve, you need to subtract the first equation from the second.
9p = 3a + 1
<u>- 7p = 2a - 3</u>
2p = 1a + 4
Now, you need to rearrange the equation so that is equal to p.
2p = a + 4
(2p)/2 = (a + 4)/2
p = (a + 4)/2
This gives you answer choice D.

Answer:
The perimeter is 20 cm.
The area is 25 cm^2.
Step-by-step explanation:
The perimeter is the distance around the figure.
This is a square, so each side is the same length.
There are four sides, so
5 + 5 + 5 + 5 = 20 cm
The area of the figure is
s^2
where s is a side
so 5 * 5 = 25 cm^2
