Answer:
x=0 x=-5 x=2
Step-by-step explanation:
4x3 + 12x2 = 40x
Subtract 40x from each side
4x3 + 12x2 - 40x=0
Factor out 4x from each term
4x( x^2 +3x-10) =0
Factor the term insdie the parentheses
What 2 numbers multiply to -10 and add to 3
5*-2 =-10
5+-2 =3
We have (x+5) (x-2)
Replace that in the equation
4x ( x+5) (x-2) =0
Using the zero product property
4x= 0 x+5 =0 x-2 =0
x=0 x=-5 x=2
we have the expressions
3.2^2-1=10.24-1=9.24
10-0.33*2=10-0.66=9.34
therefore
should be joined by a not equal sign to form an inequality
so
9.24 < 9.34
9.24 is less than 9.34
I’ve completed the question.
Would you like me to elaborate on any point?
Answer:
x=1
Step-by-step explanation:
3/4x + 1/4 =2x
3/4x=2x-1/4
3/4x-2x= -1/4
3/4x-8/4x= -1/4
-5/4x= -1/4
x= -1/4+ 5/4
x=4/4
x=1
I= interest
p= principal= $200
r= rate= 7%
t= time= 1 year
SIMPLE INTEREST FORMULA
i= prt
i= ($200)(7%)(1)
convert 7% to decimal (7% ÷ 100)
i= (200)(0.07)(1)
multiply
i= $14.00
ANSWER: $14.00 is the interest on a $200 principal at a rate of 7% for a period of 1 year.
Hope this helps! :)
