Find the LCM of 40a2b and 48ab4.​

Answers

Answer:

Step-by-step explanation:

40a²b =  2* 2 * 2 * 5 * a² * b      =  2³ * 5 * a² * b

48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴  = 2⁴ *  3 * a * b⁴

LCM = 2⁴ * 3 * 5 * a² * b⁴

       = 16 * 3 * 5 * a² * b⁴

       = 240a²b⁴

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:    

[tex]1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1[/tex]

And since -2.5 is less than -1 this statement is true. x does in fact equal 1

The length of a rectangle is 5 inches more than its vedth. The area of the rectangle is equal to
2 inches more than 4 times the perimeter. Find the length and width of the rectangle.

Answers

Answer:

The width = x = 14The length = x+5 = 14+5 = 19

Step-by-step explanation:

Let  l  = length,  w = width,  A = area =  l×w , and  P  = perimeter =  2(l+w)

Let 'x' be the width

As the length 'l' of a rectangle is 5 inches more than its width.

so the length will be = x+5

As the Area of the rectangle is equal to  2 inches more than 4 times the perimeter.

A = 4P + 2

so the equation becomes

l × w = 4×2(l+w)+2

substituting w=x, l = x+5,

(x+5)x = 8(x+5+x)+2

x²+5x = 8(5+2x)+2

x²+5x = 40+16x+2

x²+5x = 16x+42

x²+5x-16x-42 =0

x²-11x-42=0

[tex]x^2-11x=42[/tex]

[tex]\mathrm{Add\:}a^2=\left(-\frac{11}{2}\right)^2\mathrm{\:to\:both\:sides}[/tex]

[tex]x^2-11x+\left(-\frac{11}{2}\right)^2=42+\left(-\frac{11}{2}\right)^2[/tex]

[tex]x^2-11x+\left(-\frac{11}{2}\right)^2=\frac{289}{4}[/tex]

[tex]\left(x-\frac{11}{2}\right)^2=\frac{289}{4}[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

solving

[tex]x-\frac{11}{2}=\sqrt{\frac{289}{4}}[/tex]

[tex]x-\frac{11}{2}=\frac{\sqrt{289}}{\sqrt{4}}[/tex]

[tex]x-\frac{11}{2}=\frac{\sqrt{289}}{2}[/tex]

[tex]x-\frac{11}{2}=\frac{17}{2}[/tex]

[tex]x-\frac{11}{2}+\frac{11}{2}=\frac{17}{2}+\frac{11}{2}[/tex]

[tex]x=14[/tex]

similarly solving

[tex]x-\frac{11}{2}=-\sqrt{\frac{289}{4}}[/tex]

[tex]x-\frac{11}{2}=-\frac{17}{2}[/tex]

[tex]x-\frac{11}{2}+\frac{11}{2}=-\frac{17}{2}+\frac{11}{2}[/tex]

[tex]x=-3[/tex]

so

x = 14, or x = -3

As the width 'x' can not be negative.

so x = 14

Thus,

The width = x = 14The length = x+5 = 14+5 = 19

Explain how you know. Is the point (20,24) on line ℓ? Explain how you know. Is the point (80,100) on line ℓ? Explain how you know.


Answers

Answer/Step-by-step explanation:

First find the equation of the line. The graph is a proportional graph. Hence, the equation would be in the form is y = kx.

Where k I stye constant of proportionality (y/x).

Using a point on the line, (4, 5),

k = y/x = ⁵/4

Substitute ⁵/4 into y = kx.

Thus, the equation of the graph would be:

y = ⁵/4x

Plug in the value of the x and y coordinates of a point into the equation to determine if the point is on line l. If it makes the equation true, then it is a point on the line.

Thus:

✍️For the point, (20, 24), substitute x = 20, y = 24 in y = ⁵/4x

24 = ⁵/4(20)

24 = 5(5)

24 = 25 (NOT TRUE)

✅Therefore, the point, (20, 24) is not a point on line l.

✍️For the point, (80, 100), substitute x = 80, y = 100 in y = ⁵/4x

100 = ⁵/4(80)

100 = 5(20)

100 = 100 (TRUE)

✅Therefore, the point, (80, 100) IS A POINT on line l.

Express g(x) as a product of linear factors.
g(x)=

Answers

Answer:

g = 7 + 13x-1 + -5x + x2

Step-by-step explanation:

Simplifying

g(x) = x3 + -5x2 + 7x + 13

Multiply g * x

gx = x3 + -5x2 + 7x + 13

Reorder the terms:

gx = 13 + 7x + -5x2 + x3

Solving

gx = 13 + 7x + -5x2 + x3

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Divide each side by 'x'.

g = 13x-1 + 7 + -5x + x2

Simplifying

g = 13x-1 + 7 + -5x + x2

Reorder the terms:

g = 7 + 13x-1 + -5x + x2

Multiply the second equation by 3:

Then summarize  both equations 18x+9y+3x-9y=21+63

21x=84 => x=4

use x=4 in any of initial equations ,for instance in first one:

3*4-9*y=21

12-9*y=21

9y=12-21

9y=-9

y=-1
