Answer:
x = ± 6
Step-by-step explanation:
1: Subtract both sides by -54
[tex]-1.5x^2=-54[/tex]
2: Divide both sides by -1.5
[tex]x^2=36[/tex]
3: Take both sides to the 1/2 power
[tex]x= 6, -6[/tex]

the perimeter of a square field is 60 M find its area
Answer:
[tex]225m^{2}[/tex]
Step-by-step explanation:
A square has 4 sides that are equal. 60 ÷ 4 = 15
15m per side
Area of square = b x h

Are these problems real or imaginary?
Step-by-step explanation:
when the exponent is an even number, the value is -1 and real.
when the exponent is uneven (odd), then the result is i and therefore imaginary.
i¹⁴ real
i⁴³ imaginary
i⁷ imaginary
i¹⁰ real
(4 - 5i)² = 4² - 40i + 25i² = 16 - 40i - 25 = -9 -40i imaginary
(7 + 2i)(7 - 2i) = 49 - 4i² = 49 + 4 = 53 real

a function is defined by the equation f(1/2)=2X-5
Answer:
The value of f(-1) in the given equation is -10.
Step-by-step explanation:
When we see f(-1), it means that -1 is represented as our value of x. So, knowing this information, we can plug this into our given equation.
f(-1) = -3(-1)² + 2(-1) - 5
Simplify the exponent on -1.
f(-1) = -3(1) + 2(-1) - 5
Multiply -3 by 1.
f(-1) = -3 + 2(-1) - 5
Multiply 2 by -1.
f(-1) = -3 - 2 - 5
Subtract 2 from -3.
f(-1) = -5 - 5
Subtract 5 from -5.
f(-1) = -10

If the volume of cube is 8a3 + b3 + 12a2b + 6ab2. What is the
measure of the side of the cube?
Answer:
2a + b
Step-by-step explanation:
volume = 8a³ + b³ + 12a²b + 6ab² = (2a + b)³
volume = ( Side of the cube )³
( Side of the cube )³ = (2a + b)³
Side of the cube = 2a + b

Answer:
exactly 135 grandparents
Step-by-step explanation:
Here, it asks us for how many grandparents spend less than two hours online, which is 54% as that is what the sample result says. Now, you must what 54% of 250 is to find the number of grandparents who spend less than 2 hours. To do this, you make 54% a decimal and multiply it with 250. You do 0.54 x 250, which gives you exactly 135 grandparents who spend less than two hours online.

Can u solve it?
Find x,y,v and u.
Explanation:
Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.
the optimal way is to do it with Cramer's rule.
First, find the determinant and then find the determinant x, y, v, u.
Afterward, simply divide the determinant of variables by the usual determinant.
eg. [tex]\frac{Dx_{} }{D}[/tex] and etc.
I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.

Matt drew quadrilateral JKLM inscribed in a circle. Which statements could describe the angles in quadrilateral JKLM?
a. m∠L = 125°, m∠J = 35°, and m∠K = 65°
b. m∠M = 55°, m∠J = 48°, and m∠L = 132°
c. m∠J = 84°, m∠K = 12°, and m∠M = 78°
d. m∠L = 40°, m∠M = 60°, and m∠K = 120°
e. m∠K = 72°, m∠L = 44°, and m∠M = 108°
f. m∠J = 105°, m∠K = 65°, and m∠L = 75°
When a quadrilateral is inscribed in a circle, the opposite angles are supplementary
The description of the angles in the quadrilaterals are:
b. m∠M = 55°, m∠J = 48°, and m∠L = 132°d. m∠L = 40°, m∠M = 60°, and m∠K = 120°e. m∠K = 72°, m∠L = 44°, and m∠M = 108°f. m∠J = 105°, m∠K = 65°, and m∠L = 75°How to describe the anglesThe quadrilateral is given as: JKLM
The opposite angles are:
Angles J and LAngles K and MThe opposite angles are supplementary
So, we have:
[tex]J + L = 180[/tex]
[tex]K + M = 180[/tex]
