Answer:
r = 
r = 17.2 cm
Step-by-step explanation:
∵ The area of the circle A = πr²
∴ r² = A/π
∴ r = √(A/π)
∵ A = 54 cm²
∵ π = 22/7
∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm

Answer:
(3x - 5)²
Step-by-step explanation:
When we expand (3x - 5)², we get:
(3x - 5) (3x - 5)
When we multiply, we get:
9x² - 30x + 25

Have a great summer :)
First we write the expressions of each day separately:
Day 1:
you traveled x miles:
x
Day 2:
you drove 58 miles more than 3 times the thousands on Day 1:
3x + 58
Day 3:
your family went 25 fewer thousands than Day 1
x-25
Then, we have:
Day 1 + Day 2 + Day 3:
x + (3x + 58) + (x-25)
Rewriting:
x + 3x + x + 58 - 25
5x + 33
Then, for x = 100
5 * (100) + 33 = 533 miles.
answer:
5x + 33
Total miles that family traveled from home to Disney World is
533 miles
Answer:
v + u
Step-by-step explanation:
Using the rule of logarithms
log x + log y ⇔ log xy
Given
ln yx, then
ln yx = ln y + ln x = v + u
