3:5 simplest form

Answer:

x³ - 2x² - 3x + 36

Step-by-step explanation:

(x + 3)(x² - 5x + 12)

Each term in the second factor is multiplied by each term in the first factor , that is

x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis

= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms

= x³ - 2x² - 3x + 36

Answer: 13.6

Answer:

7/30

Step-by-step explanation:

5/6-3/5 ,the LCM of denominators 6 and 5 is 30 ,6 denominator divided by 30 the result from the LCM times 5 the numerator is =25, 5 denominator divided by 30 the result from the LCM times 3 is =18 ,then subtract 25 from 18 giving you 7 ,then 7/6 or seven divided by six is one whole number, one over six

Answer:

30 meters

Step-by-step explanation:

Perimeter smaller rectangle: 2(x+1)+2x = 2x+2+2x

= 4x+2

Perimeter larger rectangle: 2(4x-5)+2(3x-1) = 8x-10+6x-2

= 14x -12

2(4x+2)+2 = 14x-12

8x+4+2 = 14x - 12

8x + 6 = 14x - 12

6 + 12 = 14x - 8x

18 = 6x

x = 3

14*3-12 = 30 meters

Decimal to Fraction

Converting any terminating decimal into a fraction is fairly straightforward. You count the number of decimal places, move the decimal point that number of places to the right, and put the resulting number over "1" followed by that number of zeroes.

For instance:

Convert the decimal 0.7 into a fraction.

This decimal has one decimal place, so I move the decimal point one place to the right, to get 7. Then I put this over "1" followed by one zero (otherwise known as "10") to get: 7/10

Answer:

20.51282

Step-by-step explanation:

1. Starting by the smallest number that can be divided. 80÷39 equals to 2.

2. Now we write 2 in the answer line.

3. Multiply the result by 39. That makes us 78.

4. Now we write 78 under 800.

5. Subtract the numbers (80-78) and now we have 2.

6. Bring 0 next to our substracted number (2) so that will make it 20.

7. Divide the subtracted number with our initial value (39). That will make us a decimal number (0.512) but we will note the 0 except if you want to make it detailed then note 20.51282

8. Add the 0 next to the 2 that we writed in the start above.

9. Write the remainder (20) next to the quotient.

10. The result is 20 or to be exact 20.51282 and we have a remainder of 20.

Answer:

x=-1

Step-by-step explanation:

1/2x +1/2=x+1

Subtract 1/2x from each side

1/2x-1/2x +1/2=x-1/2x+1

1/2 = 1/2x +1

Subtract 1 from each side

1/2 -1 = 1/2x +1-1

-1/2 = 1/2x

Multiply each side by 2

2 * (-1/2) = 1/2 x*2

-1 =x

Step-by-step explanation:

A line segment can have one or more points on it. The numerical length of FG is 4

Given that:

[tex]FG = 3x - 5[/tex]

[tex]EF = x[/tex]

[tex]EG = 5x - 8[/tex]

Because point F is on EG, then:

[tex]EG = EF + FG[/tex]

So, we have:

[tex]5x - 8 = x + 3x - 5[/tex]

[tex]5x - 8 = 4x - 5[/tex]

Collect like terms

[tex]5x - 4x = 8 - 5[/tex]

[tex]x =3[/tex]

Recall that:

[tex]FG = 3x - 5[/tex]

Substitute [tex]x =3[/tex]

[tex]FG = 3 \times 3 - 5[/tex]

[tex]FG = 9 - 5[/tex]

[tex]FG = 4[/tex]

Hence, the numerical length of FG is 4

Step-by-step explanation:

x = the area in black

each triangle have area = 80

the area of the 3 triangles without combining them = 80 × 3 = 240

the total area = 210

the total area in the figure = 3 triangles area - 2x

because we have calculated 1 black area not the three of them so we need to add its area once and get rid of the others by subtracting them from the sum of the 3 triangles area

240 - 2x = 210

2x = 30

x = 15
