hello : <span>
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x1,2 =
(-b±√Δ)/2a</span></span>
factoring :
<span>ax²+bx+c = a(x-x1)(x-x2)
2 ) Δ = 0 : one solution : x1 = x2 = -b/2a</span>
factoring :
<span>ax²+bx+c = a(x-x1)²
3 ) Δ < 0 : no reals solutions... no </span>
<span>factoring </span>
Answer:
678.24 cubic in.
Step-by-step explanation:
Ok, first find the area of the base.
3.14×3^2= 28.26
Then multiply that area by the height, which is 8×3=24
24×28.26=678.24
Let me know if you got it!
Your 71,1482 doesn't make sense. But regardless,
let x = the other car's cost.
You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.
You can do $38,295 + c = $71,1482.
Or $71,1482 - $38,295 = c.
