Answer:

Step-by-step explanation:

x^2 + 3x + 2 = (x+1)(x+2)

x^2 + 4x + 3 = (x+1)(x+3)

LCM = (x+1)(x+2)(x+3) = (x^2 + 3x + 2) (x+3) = x^3 + 6x^2 + 11x + 6

Step-by-step explanation:

1st expression

x2 + 3x + 2

x²+2x+x+2

x(x+2)+1(x+2)

(x+2)(x+1)

2nd expression

x2 + 4x + 3

x²+3x+x+3

Answer: The number is 0

Step-by-step explanation:

8 = 7x + 8

Then we solve it:

8 - 8 = 7x

0 = 7x

0 ÷ 7 = x

x = 0

Answer:

-2/3

Step-by-step explanation:

h(x)=2x-6/4x^2+8

You know that h is equal to -1 so you have to plug that into x.

2(-1)-6/4(-1)^2+8. Simplify this to get -2-6/4+8 which is equal to -8/12. The GCM of 8 and 12 is 4 so you have to divide both sides by 4. This will make the fraction -2/3.

If this has helped you, please mark the answer as brainliest

Answer: [tex]h(-1) = \frac{-2}{3}[/tex]

Step-by-step explanation:

You simply substitute -1 for x

h (-1) = 2 (-1) - 6 ÷ (4 × -1² + 8)

h (-1) = (-2 - 6) ÷ (4 × 1 + 8)

h (-1) = (-2 -6) ÷ (4 + 8)

h (-1) = -8 ÷ 12 = -2 ÷ 3

h (-1) = ⁻²/₃

Answer:

your answer would be 1253in^3

Step-by-step explanation:

there are two boxes

one box has the dimensions 7,5,5

the other has the dimensions 14,11,7

you would have to multiply all the dimensions

7*7*5=175

14*11*7=1078

then you add the two products together

1078+175=1253

hope this helps! have a nice day :)

Answer:

Answer:

y=-1/4x+5

Step-by-step explanation:

Use the point-slope form which is y-y1=m(x-x1) where m is the slope. In this case, y is equal to 3, and x is equal to 8, and the slope is equal to -1/4. Therefore, the equation will be equal to y-3=-1/4(x-8). Simplify that to get        y-3=-1/4x+2. Simplify this again to get y=-1/4x+5. Therefore, the equation is y=-1/4x+5.

Answer:

y = -1/4x + 5

Step-by-step explanation:

Since the lines are parallel, they have the same slope, which is -1/4

Use the point-slope form to do this problem

[tex]y - y_{1} = m(x - x_{1})[/tex]  Memorize this form. OK?

y - 3 = -1/4(x - 8)

4y - 12 = -1(x - 8) = -x + 8

4y = -x + 20

y = -1/4x + 5

Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2

(All of the above are rounded off to one decimal place)

The given data are : 20, 22, 26, 27, 30, 31, 35, 35

We know that, mean = (sum of samples)/(no. of samples)

                                   = (20+22+26+27+30+31+35+35)/8

                                   = 226/8 = 28.25 = 28.3 (approx)

Here, median = (sum of 4th & 5th sample)/2

                       = (27+30)/2 = 57/2 = 28.5

Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35

Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8

= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8

= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)

Answer:

88 ft^2

Step-by-step explanation:

For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions

1 ft by 8 ft,

two opposite faces with dimensions

1 ft by 4 ft,

and two opposite faces with dimensions

4 ft by 8 ft.

We find their area and add them.

SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft

SA = 16 ft^2 + 8 ft^2 + 64 ft^2

SA = 88 ft^2
