Answer:
15x+45-2x=15x-2x-10
13x+45=13x+10
13x-13x=10-45
if you simplify further
you will not get an answer there is a mistake in the question
Answer:
A. None correct
Explanation:
We can use the <em>power rule</em> for logarithms
:
The logarithm of the nth power of a quantity is n times the logarithm of the quantity.
In symbols, ln(xⁿ) = nlnx.
Apply the power formula.
This answer is not in your list.
The correct answer is A. None correct.
A) a bench --- C=2πr, if r=π, then C=2π²=19.74,
if you need to use π=3.14, then C=19.72 ft
cover ---- area =πr²=π³=31.01 ft²
if you need to use π=3.14, then A=30.96 ft²
B) R=2.5r
C=2πR, if R=2.5π, then C=2*2.5π²=5π²=49.35 ft
if you need to use π=3.14, then C=49.30 ft
how much longer = 49.35 -19.74=29.61 ft
You add 3 2/7. 7/1-3 5/7= 3 2/7
