Answer:
Step-by-step explanation:
perimeter P= 2L+2W
360=2(L+W) divide by 2
180=L+W
we know the L=100
180=100+W
W=80
Answer:
6
Step-by-step explanation:
The number on the right side of the equal side represents the radius, HOWEVER, it is squared, therefore you must square root it to get 6
First, convert 2m into cm by multiplying by 100 so the ratio is now 40:200, then 40 goes into 200 5 times so the ratio is 1:5. Hope that helped!
Answer:
C
Step-by-step explanation:
Using the rules of logarithms
loga + logb = log(ab)
loga - logb = log(
)
log
⇔ nlogx
Given
4lnx + ln3 - lnx
= 3lnx + ln3
= lnx³ + ln3
= ln(x³ × 3)
= ln(3x³) → C
Answer:
-5(x² -2x +3)
Step-by-step explanation:
5 is a factor common to all of the coefficients. It is convenient to have the x² coefficient be positive in the factored form, so the result of factoring out -5 is ...
... -5((-5x²/-5) +(10x/-5) +(-15/-5)) = -5(x² -2x +3)
