Find all real solutions and show work:
2x^3-3x^2+18x-27=0
Answers
Given:
The given equation is
[tex]2x^3-3x^2+18x-27=0[/tex]
To find:
All the real solutions.
Solution:
We have,
[tex]2x^3-3x^2+18x-27=0[/tex]
It can be written as
[tex]x^2(2x-3)+9(2x-3)=0[/tex]
[tex](2x-3)(x^2+9)=0[/tex]
Using zero product property, we get
[tex](2x-3)=0[/tex] and [tex](x^2+9)=0[/tex]
[tex]2x=3[/tex] and [tex]x^2=-9[/tex]
[tex]x=\dfrac{3}{2}[/tex] and [tex]x=\pm\sqrt{-9}[/tex]
We know that [tex]x=\pm\sqrt{-9}[/tex] is an imaginary number because there is a negative sign under the square root.
Therefore, [tex]x=\dfrac{3}{2}[/tex] is the only real solution of the given equation.

Work out the number of years of investment for each return.
a. £3000 invested at 3% simple interest returns £3720
Answers
Answer:
41 years approx
Step-by-step explanation:
Given data
P= £3000
R=3%
Simple Interest= £3720
Time=???
We know that from the simple interest expression
SI= PRT/100
substitute
3720= 3000*3*T/100
Make T subject of the formula
T= 3720*100/3000*3
T= 372000/9000
T= 41.33
Hence the number of years is 41 years approx

could model this information, Solve the quadratic equation to determine a possible value for x,
PLS HELP ME AND IF YOU CAN SHOW HOW U GOT THE ANSWER IF NOT THATS OKAY!!! ILL ALSO MARK YOU BRANLIEST IF YOU HELPED ME!!! <333
Answers
Answer:
Step-by-step explanation:
The length is (x-1), not (2-1).
area = (x-1)(x+3) = 12 ft²
x²+2x-3 = 12
x²+2x-15 = 0
(x+5)(x-3) = 0
x = -5, 3
-5 is an extraneous solution, so x=3.
Length = x-1 = 2 feet
Width = x+3 = 6 feet

Answers
Answer:
b=9 and b=-21
Step-by-step explanation:
first step: move 195 to the other side by adding to get:
b^2+12b=189
now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36
b^2+12b+36=189+36
next factor b^2+12b+36.
(b+6)^2=225
square root both sides to get:
b+6=15 and b+6=-15
solve by subracting 6 to both sides and you get the 2 final answers.
b=9 and b=-21

need answer. pls help
Answers
Answer: 28 degrees
Step-by-step explanation:
Since angle KJL = LJM then that means angle 7x=3x+16
First we need to solve for x
7x=3x+16
4x=16
x=4
now we can input it into either equation to solve for the angle KJL
7(4)= 28 so the angle is 28 degrees

-18+x=-x+12
This one ??
Answers
Answer:
X = 15
Step-by-step explanation:
Let's solve your equation step-by-step.
−18+x=−x+12
Step 1: Simplify both sides of the equation.
x−18=−x+12
Step 2: Add x to both sides.
x−18+x=−x+12+x
2x−18=12
Step 3: Add 18 to both sides.
2x−18+18=12+18
2x=30
Step 4: Divide both sides by 2.
