<h3>What is a Triangle?</h3>
A triangle is a shape that has three sides. The sides can be measured using a ruler.
The sides of the triangle in the image shown have side lengths as measured by the ruler beside each of the sides, which are 5 cm, 12 cm, and 13 cm.
Therefore, the three side lengths of the triangle in the diagram are: 5 cm, 12 cm, and 13 cm.

Answer:
290 + 5m = 985
Step-by-step explanation:
<u>Given information</u>:
- Initial payment = $290
- Total payment = $985
- Extra amount each month = m
- Length of rental = 5 months
From the <u>given information</u>, we can create the following <u>equation</u>:
Initial payment <u>plus</u> extra amount each month for 5 months <u>equals</u> total payment.
⇒ 290 + 5m = 985
<u>To solve the equation</u>:
Subtract 290 from both sides:
⇒ 290 + 5m - 290 = 985 - 290
⇒ 5m = 695
Divide both sides by 5:
⇒ 5m ÷ 5 = 695 ÷ 5
⇒ m = 139
Therefore, the extra amount George paid each month was $139.
