[tex]24x^{2}+bx^{2} =25x^{2}[/tex]
Answer:
x = 0
Step-by-step explanation:
Subtract 25x^2 from both sides
24x^2 + bx^2 - 25x^2 - 25x^2
Simplify
bx^2 - x^2 = 0
Factor bx^2 - x^2: x^2(b - 1)
bx^2 - x^2
Factor out common term x^2
= x^2 (b - 1)
x^2(b - 1) = 0
Using the Zero Factor Principle: If ab = 0 then a = 0 or b = 0
x^2 = 0
Apply rule x^n = 0 x = 0
x = 0

Find the area of an equilateral triangle with sides of length 24 inches in simplest
form?
Answer:
B. 144√3 in².
Step-by-step explanation:
Given the following data;
Sides of length = 24 inches
Mathematically, the area of an equilateral triangle is given by the formula;
A = √3 * s²/4
Where, s represents the sides of length.
Substituting into the formula, we have;
A = √3 * 24²/4
A = √3 * 576/4
A = √3 * 144
A = 144√3 in²

If MK = 10 m, find the length of MKL.
The length of arc MKL in the image given is: 19.02 m.
What is the Arc Length?Arc length = ∅/360 × 2πr, where r = 1/2(diameter of circle).
∅ = 180 + (90 - 52) = 218°
Radius (r) = 10/2 = 5 m
Arc length of MKL = ∅/360 × 2πr = 218/360 × 2π(5)
Arc length of MKL = 19.02 m
Therefore, the length of arc MKL in the image given is: 19.02 m.

Answer:
40 units
Step-by-step explanation:
The slanted side is the hypotenuse of a triangle that is 8 units high and 6 units wide. Its length can be found from the Pythagorean theorem:
d² = 6² + 8² = 100
d = √100 = 10
The perimeter is the sum of side lengths. Those lengths can be found by counting grid squares. Clockwise from the upper left corner, the sum of side lengths is ...
P = 8 + 10 + 14 + 8

Answer:
x = 45°Step-by-step explanation:
Given ,
Angles of the triangle are = 90° , 45° and x
Therefore,
x will be
=> 90° + 45° + x = 180° [Since angle sum property of triangle]
=> x = 180° - 90° - 45°
=> x = 180° - 135°
=> x = 45° (Ans)

Marquise has 200 meters of fencing to build a rectangular garden.
The garden's area (in square meters) as a function of the garden's width x
(in meters) is modeled by:
A(x)=-x^2+100x
Answer:
2500
Step-by-step explanation:
The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.
What is a rectangle?It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
Marquise has 200 meters of fencing to build a rectangular garden.
The garden's area (in square meters) as a function of the garden's width x (in meters) is modeled by:
A(x)= - x² + 100x
The perimeter of the rectangle = 2( length + Width)
200 = 2( length + Width)
100 - x = L
The area of the rectangle = length × Width
= x(100 - x)
= (-x)²+ 100x
So, (-x)²+ 100x where, a = -1 and b = 100
w = -100/2(-1)
w = 50
The area of the rectangle = (-x)²+ 100x
= (-50)²+ 100(50)
= 2500
Thus, The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.

The price of a cell phone is usually $240 Ella mom buys one of these cell phones when the discount is 25 how much did Ella mom save?
Answer:
$60
Step-by-step explanation:
$240 = 100%
Discount = 25%
100% - 25% = 75%
75% as a decimal is 0.75
Multiply:
240(0.75) = 180
You could also do 3/4 of 240 because 0.75 is 3/4
To find out how much she saved, let's subtract the sale price from the original price:
240 - 180 = 60
Ella's mom saved $60 from the discount

PLSSS HELLPPPPP!!!!!!! Find the measure of the missing angle.
Answer:
86 degrees
Step-by-step explanation:
The total angles of a quadrilateral add up to 360 degrees, so if you do 360-134-50-90, you get 86, which is your answer.
Answer:
x is 86
Step-by-step explanation:
To solve we will use the equation s = (n-2) 180
s is the sum of all the angles, and n is the number of sides the shape has.
We do not know what s is yet, and since this is a 4 sided figure we will have to solve it like this:
s= (4-2) 180
s= 2(180)
s= 360
Since we now know all the angles added together will equal 360 we can now solve for x. We will solve by adding up all the angles together plus x like this:
134+ 90+ 50+x = 360
274 + x = 360
-274 -274 360-274 = 86
X = 86
