If (x^2 -10) is one of the factors, that can be further factored into:
(x - sqrt(10) ) * (x+sqrt(10)) =0
making 2 of the 4 solutions equal:
3.1623 and -3.1623
I then used an algebraic long division calculator
http://calculus-calculator.com/longdivision/
to calculate:
<span>x^4 + 5x^3 ‒ x^2 ‒ 50x ‒ 90 divided by x^2 -10 which equals
</span>x^2 + 5x + 9
Using the quadratic formula, the roots of that equation are:
x = -5 + sqrt (-11) / 2
and
x = -5 - sqrt (-11) / 2
Both of those roots are not real.
I tried using online graphing calculators for x^4+5x^3-x^2-50x-90=0 but none worked.
2. For this equation,
<span>3x^2 ‒ 8x + k = 0
I used my OWN quadratic formula calculator
http://www.1728.org/quadratc.htm
and found that real roots no longer exist after "k" is greater than 5.3

The formula to finding the Volume of a rectangular prism is
W=width L=length H=height
You have 3 rectangular prisms, you need to find the volume of each one and add them together.
(Going from left to right in rectangular prisms)
(3ft x 2ft x 2.5 ft) + (3ft x 1.75ft x 3ft) + (4ft x 4ft x 2.5ft) = Your answer
I hope this helps :)
(Also, You don't need to use the formula as directly stated, the way I showed for your problem is
As long as you don't multiply the wrong numbers together{as in mixing up the #s from other rectangular prisms} you should be perfectly fine (: )

Answer:
set the equations to ____ = 360/90
Step-by-step explanation:
for example, a, the equation is 2a + 90 = 360
-90 -90
---------------------
2a = 270
/2 /2
a=135
