Answer:
×2-47=0 Mark me as brainlist
Answer:
Step-by-step explanation:
x^2+8x-6=0
(x^2+8x+16) -6=0+16
(x+4)^2-6=16
(x+4)^2=22
x+4= sqaure root of 22
x= -4 + or minus sqaure root 22
Answer:
Option 2 is correct.
Step-by-step explanation:
For right triangle
The pythagoras theorem should satisfy
The square of longest side should be equal to the sum of square of other two sides
Case1:
We have 
If we substitute in the formula
we get:
which does not satisfy the condition.
Case2:
We have 
If we substitute in the formula
we get:
34=25+9
which satisfies the condition.
Hence, option 2 is correct.
Well, it cant be option B because then it wuld be half the time (180 mins.)
It cant be option D becasue then it would be over 360 mins, seeing that it only took 8 mins to type 360
And it cant be option C beacuse it would be too small, if 4 mins is to small then 3 mins is worse
Your answer would be A 5 minutes it's just a little bit above 4 mins(half)
Answer:
a) 1/27
b) 1
c) 125
Step-by-step explanation:
a) (9^(0.5b))/(3^a)
(3²)^(0.5b) ÷ (3^a)
(3^b) ÷ (3^a)
3^(b - a)
a - b = 3
b - a = -3
3^(-3)
1/27
b) (27^(1/3b)) /(9^(0.5b))
(3³)^(b/3) ÷ (3²)^(0.5b)
(3^b) ÷ (3^b)
1
c) ( 125^(1/3a))/(25^(1/2b))
(5³)^(a/3) ÷ (5²)^(b/2)
5^a ÷ 5^b
5^(a - b)
5³
125
