The equation k = √3abc + a² - b² + c² - 5b is an algebraic expression
The value of k = √3abc + a² - b² + c² - 5b when a = -2, b = -2 and c = 3 is 25
How to solve the expression?The equation of k is given as:
k = √3abc + a² - b² + c² - 5b
Where
a = -2, b = -2 and c = 3
Substitute a = -2, b = -2 and c = 3 in the equation of k
k = √(3 * -2 * -2 * 3) + (-2)² - (-2)² + 3² - 5*-2
Evaluate the root expression
k = 6 + (-2)² - (-2)² + 3² - 5*-2
Evaluate the exponents and the products
k = 6 + 4 - 4 + 9 + 10
Evaluate the sum and the difference
k = 25
Hence, the value of k = √3abc + a² - b² + c² - 5b when a = -2, b = -2 and c = 3 is 25

the cost of 7 toys is AED 294. the cost of 5 toys. (Unitary method)
Answer:
AED 210
Step-by-step explanation:
If the cost of 7 toys is AED 294, this is written as;
7 toys = AED 294
To get the cost of 5 toys, this is written as;
5 toys = x
Divide both expressions
7/5 = 294/x
Cross multiply
7x = 5 * 294
7x = 1470
x = 1470/7
x = 210
Hence the cost of 5 toys is AED 210

The width of a rectangle is
(4x + 1) in.
The length of the rectangle is three times the width. Find the area of the rectangle in terms of the variable x.
Answer:
48x² + 24x + 3
Step-by-step explanation:
Width = (4x + 1) in
Length = 3 *width = 3*(4x + 1) = 3*4x + 3*1
= (12x + 3) in
Area of rectangle = length * width
= (12x + 3) (4x + 1)
= 12x *4x + 12x *1 + 3*4x + 3*1
= 48x² + 12x + 12x + 3
= 48x² + 24x + 3

Write a second equation whose graph goes through (0,1) so the system has no solutions.
Answer:
y = 5x + 1
Step-by-step explanation:
Hello There!
Equations that have no solutions are parallel
So the line we are going to create an equation for has the same slope as the line drawn
To find the slope we do change in y divided by change in x
as y goes 5 x goes up 1
so the slope is 5/1 or 5
The requirements for the equation is it has to go through the points (0,1)
The ordered pair listed is the y intercept so the equation would be
y = 5x + 1

Sam and Ella were running in a race. Sam ran ⅞ of a mile and Ella ran 5/10 of a mile. At the end of the race they wanted to compare how far they ran. Ella said they could compare the fractions by comparing each fraction to ½. Show how Ella could compare 5/10 and ⅞ to ½ . Then explain who ran further and how you know.
Answer:
ELLA
Step-by-step explanation:
Given that :
Distance covered by Ella = 5/10
Distance covered by Sam = 7/8
Comparing each distance to 1/2
Ella = 5/ 10 = 1/2 ; 1/2 = 1/2 = 0.5
Sam = 7/8 = 0.875 ; comparing with 1/2
0.875 > 0.5
Given
Sam ran farther Than ELLA
Because 0.875 > 1/2
0.875 - 0. 5 = 0.375

Answer: roots are 2, -2, -3, and 3
Step-by-step explanation:
I'm presuming the equation is x^4-9x^2-4x+12
so first group the equation by factoring out the GCF of the first two terms and last two terms
x^2(x^2-9)-4(x-3)
x^2(x-3)(x+3)-4(x-3)
(x^2-4)(x-3^2)(x+3)
(x-2)(x+2)(x+3)(x-3)^2
So
The potential roots of the function p(x) = x⁴ - 9x² - 4x + 12 are x = 1, -2 and 3.
What is the degree of a polynomial?
Degree of a polynomial is the highest power of the variable in that polynomial. For example, in a cubic polynomial, the variable [x] has the highest power of 3.
Given is the following function with degree of 4 as -
x⁴ - 9x² - 4x + 12
We will plot the graph and find the roots of this function. The number of x - intercepts [coordinates where the graph cuts the x axis] will give us the roots or zeroes of the polynomials. Refer to the graph attached, it shows that the graph intercepts the x - axis at three different coordinates which are → x = 1, x = -2 and x = 3. Hence, these three values of [x] are the potential roots of the function p(x) = x⁴ - 9x² - 4x + 12.
Therefore, the potential roots of the function p(x) = x⁴ - 9x² - 4x + 12 are x = 1, -2 and 3.

Scrooge-
Oh! But he was a tight-fisted hand at the grindstone! Scrooge! a
squeezing, wrenching, grasping, scraping, clutching, covetous old
sinner! Hard and sharp as flint, from which no steel had ever struck out
generous fire; secret, and self-contained, and solitary as an oyster. The
cold within him froze his old features, nipped his pointed nose, shrivelled
his cheek, stiffened his gait; made his eyes red, his thin lips blue; and
spoke out shrewdly in his grating voice. A frosty rime' was on his head,
and on his eyebrows, and his wiry chin. He carried his own low
temperature always about with him; he iced his office in the dog-days;
and didn't thaw it one degree at Christmas.

Answer:
JL = 9√13
Step-by-step explanation:
All of the triangles in this geometry are similar:
∆MKL ~ ∆MLJ ~ ∆LKJ
Corresponding sides of similar triangles are proportional, so you can write the relations ...
JL/JM = JK/JL ⇒ JL² = JM·JK
LM/JM = KM/LM ⇒ LM² = JM·KM
Using the second expression to find JM, we have ...
JM = LM²/KM = 18²/12 = 27
We know that JK = JM +KM. Then the first expression can be ...
JL² = 27·(27 +12) = 9²·13
JL = 9√13
