Hiya!

x is going to work out to 25.

———————————————

so first put the numbers into the equation you’ve been given.

pressure is 3, force is 1500 so 3=1500/area

then rearrange this equation so that you’re finding area.

area=1500/3

and 1500/3 gives you 500.
so 500 is the area.

area is length multiplied by width, so 20 multiplied by x.
total/width will give length, so 500/20 will give x.
500/20=25

so x is 25.

Find the discriminant, and determine the number of real solutions. then solve x^2 +8x+20=0

vodomira [7]

Answer:

Part 1) The quadratic equation has zero real solutions

Part 2) The solutions are

$x_1=-4+2i$ and $x_2=-4-2i$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}+8x+20=0$

$a=1\\b=8\\c=20$

The discriminant is equal to

$D=(b^{2}-4ac)$

If D=0 -----> the quadratic equation has only one real solution

If D>0 -----> the quadratic equation has two real solutions

If D<0 -----> the quadratic equation has two complex solutions

Find the value of D

$D=8^{2}-4(1)(20)=-16$ -----> the quadratic equation has two complex solutions

Find out the solutions

substitute the values of a,b and c in the formula

$x=\frac{-8(+/-)\sqrt{8^{2}-4(1)(20)}} {2(1)}$

$x=\frac{-8(+/-)\sqrt{-16}} {2}$

Remember that

$i=\sqrt{-1}$

$x=\frac{-8(+/-)4i} {2}$

$x_1=\frac{-8(+)4i} {2}=-4+2i$

$x_2=\frac{-8(-)4i} {2}=-4-2i$

PLEASE HELP WITH ALGEBRA QUESTIONS!!

kenny6666 [7]

1. (f+g)(x) = f(x) +g(x)
.. = (x^2-36) +(x^3+2x^2-10)
.. = x^3 +3x^2 -46

2. (f•g)(x) = f(x)•g(x)
.. = (x^4-9)•(x^3+9)
.. = x^7 +9x^4 -9x^3 -81

3. (f-g)(x) = f(x) -g(x)
.. = (x^3-2x^2+12x-6) -(4x^2-6x+4)
.. = x^3 -6x^2 +18x -10

Next two terms 5, 3, 1.8, 1.08

Alenkinab [10]

Guessing geometric
so

hmm
5 times what=3
divide both sides by 5
what=3/5
what=0.6
each term is multiplied by 0.6

so
1.08 times 0.6=0.648
0.648*0.6=0.3888

the next 2 terms are 0.648 and 0.3888
