4/(√<em>x</em> - √(<em>x</em> - 2)) × (√<em>x</em> + √(<em>x</em> - 2))/(√<em>x</em> + √(<em>x</em> - 2))
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / ((√<em>x</em>)² - (√(<em>x</em> - 2))²)
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / (<em>x</em> - (<em>x</em> - 2))
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / (<em>x</em> - <em>x</em> + 2)
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / 2
= 2 (√<em>x</em> + √(<em>x</em> - 2))

Answer:
Solution:
<u>Let's use PRT/100 to find the simple interest.</u>
- 3500 x 7.5 x 3/100 = Interest
- → 35 x 7.5 x 3 = Interest
- → 35 x 7.5 x 3 = Interest
- → $787.5 = Interest
Hence, the simple interest is $787.5.
Answer:
30, 10
Step-by-step explanation:
length=x
wdith=y
xy=300, x=3y
replace x with 3y in the first equation to get
3y^2=300
y^2=100
since you cant have a negative side of a garden, y=10. x=30.
