Answer:
I say yes because when u solve it and flip the ( )'s, you get the same answer.
Step-by-step explanation:
Work:
(4/3 + 2/3) + 2
6/3 + 2
2 + 2
= 4
4/3 + (2/3 + 2)
4/3 + 8/3
12/3
= 4
Hope this helps!!
The answer has to be 144 since it is the only one smaller than 180
Answer:
The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .

Answer:
Step-by-step explanation:
1 ) k²-8k = 0
k(k-8)=0
k = 0 or k=8
2) a²+5a=0
a(a+5) = 0
a=0 or a = - 5
3 ) 6n²+5n-25=0
delta = b²-4ac b =5 and a = 6 and c= - 25
delta = 5²-4(6)(-25) = 625 = 25²
n 1 = (-5+25)/12 = 20/12 = 5/3
n 2 = (-5-25)/12 = - 30/12 = -5/2
same method for 4) and 5)
