What is x2-4x=2x+24 equal to 0

Mathematics

Valentin [98]4 years ago
3 0
Make equal to zero
x^2-4x=2x+24
minus 2x both sides
x^2-4x-2x=24
minus 24
x^2-6x-24=0
comlpete the square
isolate x^2 and x term
(x^2-6x)-24=0
take 1/2 of -6 and square it (-6/2=-3 (-3)^2=9) and add to both sides inside parethaes
(x^2-6x+9)-24=9
factor perfect square
(x-3)^2-24=9
add 24 both sides
(x-3)^2=33
sqrt both sides
x-3=+/-√33
add 3 to both sides
x=3+/-√33

x=3+√33 or 3-√33

Triangle ABC has a perimeter of 22cm I WILL MARK YOU AS BRAINLIEST
Andreyy89

Answer:

Step-by-step explanation:

Number of vertices

3

Variable constraints

a>0 and b>0

Diagonal lengths

(data not available)

Height

b

Area

A = (a b)/2

Centroid

x^_ = (a/3, b/3)

Mechanical properties:

Area moment of inertia about the x-axis

J_x invisible comma x = (a b^3)/12

Area moment of inertia about the y-axis

J_y invisible comma y = (a^3 b)/12

Polar moment of inertia

J_zz = 1/12 a b (a^2 + b^2)

Product moment of inertia

J_x invisible comma y = -1/24 a^2 b^2

Radii of gyration about coordinate axes

r_x = b/sqrt(6)

r_y = a/sqrt(6)

Distance properties:

Side lengths

a | sqrt(a^2 + b^2) | b

Hypotenuse

sqrt(a^2 + b^2)

Perimeter

p = sqrt(a^2 + b^2) + a + b

Inradius

r = 1/2 (-sqrt(a^2 + b^2) + a + b)

Circumradius

R = 1/2 sqrt(a^2 + b^2)

Generalized diameter

sqrt(a^2 + b^2)

Convexity coefficient

χ = 1

Mean triangle area

A^_ = (a b)/24

A cricket bat costs $129.25 after tax has been added on at 17.5%. How much did the cricket bat costs before tax was added
Andreyy89

Answer:

The price before tax was $110

Step-by-step explanation:

Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b:  b + 0.175b = $129.25.  Combining the b terms, we get:

1.175b = $129.25.  Solving for b by dividing both sides by 1.175, we get

b = $110.  The price before tax was $110.
