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
Answer:
Step-by-step explanation:
A: dividend;
B: divisor;
C: quotient
IT means that u need to subtract 4 from 3/7 of y i.e
<span>3/7 of y = 3Y/7 </span>
<span>subtract 4 from it we get </span>
<span>{(3Y/7)- 4}
hope this helps, Gastondekota! :-)</span>
Answer: 6 1/5 miles
Step-by-step explanation:
Here's the complete question:
On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.
The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:
= Distance to supermarket = 1¾ + ¼ = 2 miles
Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles
Total distance = 2 + 4 1/5 = 6 1/5 miles
U r going to subtract 3 from each side of the equation....leaving you with :
x^2 + 2x = -3
