Step-by-step explanation:
first number=x
second number=x+2
third number=x+4
(x+2)(x+4)=35
x(x+4)+2(x+4)=35
x²+4x+2x+8=35
x²+6x+8=35
x²+6x=35-8
x²+6x=33
x²+6x-33=0
using that, you can find the first number,
then use the data to find the other two.
Answer:
29.5 mm
Step-by-step explanation:
We are told that the average monthly rainfall for 6 months was 28.5 mm.
Thus, total for the 6 months = 28.5 × 6 = 171 mm
Now, we are told that it rained 1 mm extra each month.
So extra for the six months = 1 × 6 = 6mm
New total for 6 months = 171 + 6 = 177 mm
So, new average for 6 months = 177/6 = 29.5 mm
Answer:
123 is not a multiple of 9, while all others are
99 is a multiple of 11, while all others are not
Answer:28
Step-by-step explanation:
3^x=5
3^2x+3
(3^x)^2 + 3
Substitute 3^x=5 in (3^x)^2 + 3
5^2 + 3
5x5+3=28
3 1/4 inches is the mixed number
