It is beans and Obama 3+8 and u have to simplify for negative
Answer:
√29
Step-by-step explanation:
We are here given that ,
Now square the first equation ,
⇒ a - b = 3
⇒ ( a - b)² = 3²
⇒ a² + b² - 2ab = 9
⇒ a² + b² - 2(5) = 9
⇒ a² + b² -10 = 9
⇒ a² + b² = 9 + 10
⇒ a² + b² = 19
⇒ a² + b² + 2ab = 19 + 2(5)
⇒ (a + b)² = 19 + 10
⇒ ( a + b)² = 29
⇒ a + b = √29 .
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
