Answer:
factor left the side of the equation
(2k_9)(k+2)=0
set factors equal to 0
2k_9=0 or k+2=0
the answer is K= 9/2 or K =-2
List the first few prime numbers.
2, 3, 5, 7, 11, 13, ...
We want the product of the three lowest prime numbers to form the least whole number.
2*3*5 = 30
This the least whole number.
Answer:
The number is 30.
It factors into 2, 3 and 5.
Answer:
A = 145cm
Step-by-step explanation:
A+B+C = 445cm
b = 1/2c
a = b+45 = 1/2c + 45
445 = c + (0.5c) + (0.5c + 45)
445 = 2c + 45
445 - 45 = 2c
400/2 = c
c = 200cm
a = 1/2c + 45 = 1/2*200 + 45 = 100 + 45 = 145cm
Hey!
Lets take the square root of all these answer choices.
√63 ≈ 7.9
√99 ≈ 9.4
√83 ≈ 9.1
√10 ≈ 3.2
So if we look at all the answer choices square root, the answer that is the closest to 9 is √83.
Therefore, your answer will be C. square root of 83.
Hope this helps! :)
Just do the whole process backwards
700*0.01=7
7-2.84=4.16
4.16/0.8=5.2
5.2+1.05=6.25
