Answer:
4 and 9 or 4:9 or 4/9
Step-by-step explanation:
Divide both terms by the GCF, 4:
16 ÷ 4 = 4
36 ÷ 4 = 9
The ratio 16 : 36 can be reduced to lowest terms by dividing both terms by the GCF = 4
Answer:
x= -14
Step-by-step explanation:
-x+3x-x=-8-6
x= -14
Answer:
Add 4 on both sides.
In the equation there is a -4.
If -4+4=0, that is how you would get rid of the -4.
But, you need to add 4 to 29 to really get rid of the -4.
So, 29+4 is 33.
b=33
Answer:
After 7.5 seconds and a height of 0
Step-by-step explanation:
9x² - 6x + 1
1st method:
Factor 9, you will get 9( x² - 6/9 x+ 1/9). Or 9(x² -2/3 +1/9)
but 9(x² - 2/3 x + 1/9) this can be written as 9(x - 1/3)²
2nd method: Solve this quadratic equation by finding the zero values.
x' =[-b + √b² - 4ac] / 2a and x" = =[-b - √b² - 4ac] / 2a
a=9; b=-6; c=1, hence [6+√(36-(4)(9)]/2(9) = (6 - √0)/18 x = 6/18 = 1/3
even x" =1/3
and ax²+bx + c = a(x-x')(x-x") =9(x-1/3)²
