Answer:
x=-0.544727
x=2.294727
Step-by-step explanation:
Given quadratic equation to solve:
To solve, use the quadratic formula
x= -b ± b² - 4ac / 2a
Substitute your values for a, b, & c and solve
x= -7 ± 7² - 4·(-4)·5 / 2·(-4)
x= -7 ± 49 - -80/-8
x= -7 ± 129/-8
Then, reduce the problem
x= -7/-8 ± 129/-8
x=-0.544727
x=2.294727

I'll teach you how to solve f(x)=0x63 - 52x – 96</h3>
----------------------------------------------------------
f(x)=0x^3 - 52x – 96
Apply rule:
0 * a= 0
0-52x-96
Group like terms:
-52x+0-96
Add/subtract the numbers:
0-96= -96
-52x-96
Your Answer Is -52x-96
plz mark me as brianliest if this helped :)
Answer:
(a)2(89x+84)
(b)
Step-by-step explanation:
The dimensions of the larger rectangular field are:
- Length=5x + 12; Width
= 9x + 14.
The dimensions of the smaller rectangular soccer field are:
(a)Area of the part of the field that is outside the soccer field
=Area of the larger rectangular field - Area of the Soccer Field
=(5x+12)(9x+14)-5x(9x)
=(5x)(9x)+70x+108x+168-5x(9x)
=178x+168
=2(89x+84)
(b)Radius of the Semicircular Fountain =2x
From Part (a),
Area of the larger rectangular field - Area of the Soccer Field=178x+168
Area of the Semicircular Fountain =
Area of the Field that does not include the soccer field or the fountain.
=Area of the larger rectangular field - Area of the Soccer Field-Area of the Semicircular Fountain

Answer:
= 
Step-by-step explanation:
In this case in order to simplify we need to know what the "power rule of exponents" is. Simply speaking this rule states that when you raise a power to a power you multiply the exponents. So in our case we ill get the following
= 
In order to get 42 we used the power rule which I mentioned earlier.
Answer:
Step-by-step explanation:
hello :
16t²+120 = y
16t² = y -120 so : t² = (y-120)/16
if : y-120 ≥ 0 t = ±√((y-120)/16)
