20.5 is the answer because when you divide 98.4 by 4.8 you get 20.5 as the answer
Answer:
1 Regroup terms.
2x²−5=−6x
2 Move all terms to one side.
2x² −5+6x=0
3 Use the Quadratic Formula.
x=
−6+2√19/ 4
−6−2√19 /4
4 Simplify solutions
x=
-3−√19 /2
-3+√19/3
Decimal Form: 0.679449, -3.679449

Answer:
= (x+4) (x-7)
Step-by-step explanation:
x²-3x -28
Product = -28
Sum = -3
numbers = -7 and 4
Thus;
x²- 3x -28 ; replacing -3x with -7x and 4x
x²-7x +4x -28
x(x-7) + 4(x-7)
<u>= (x+4) (x-7) </u>
Answer:
47/6
Step-by-step explanation:
Given that :
Time taken to paint 3 cars = 4 hours
Time taken to paint 2 trucks = 5 hours
How long will it take him to paint 4 cars and a truck
If 3 cars = 4 hours ;
Then ;
1 car = (4/3)hours
If 2 trucks = 5 hours
Then;
1 truck = (5/2) hours = 2 1/2 hours
Time required To paint 4 cars :
4 × (4/3) = 16/3 hours
Time required to paint 1 truck :5/2 hours
Total time required :
(16/3 + 5/2) = (32 + 15) / 6 = 47/6
Well, it was good that you did subtract A from B to get
0=x^2-152x
then factor out the x (what do you mean it cannot be factored?)
0=x(x-152)
x=0 or 0=x-152 so x=152
so on day 0 and day 152
