Answer:

7 \leq -\displaystyle\frac{d}{5}

-7 \geq \displaystyle\frac{d}{5}

Step-by-step explanation:

We have to form an inequality with the given information.

The quotient of a number d and -5 is given by:

\displaystyle\frac{d}{-5} = -\displaystyle\frac{d}{5}

Now, this inequality is at most 7 that is the above expression can have the value of seven or less.

This can be written as:

7 \leq -\displaystyle\frac{d}{5}

Multiplying both sides by -1, we have:

-7 \geq \displaystyle\frac{d}{5}

Thus, 7 \leq -\displaystyle\frac{d}{5} is the required inequality.

What is the greatest common factor of the terms of the polynomial below? 8x^4 - 12x^3 + 20x^2
Daniel [21]

Answer: I think the greatest common factor is 4x^2

Step-by-step explanation:

Find the numerical common factors. Which are 8, -12, and 20. Find the variable common factors for x^4, x^3, and x^2. Multiply them together. Then break down the factors on both sides and pick the biggest one. Finally multiply them together. (I’m sorry, I’m very bad at explaining things.)

The longest side of a triangle is 3 in. longer than the shortest side. The medium side is 2 in. longer than the shortest side. I
Olenka [21]

s = length of the shortest side of the triangle

m = length of the medium side of the triangle

l = length of the longest side of the triangle

(you can use different variables like l, w, h, x, y.......)

Perimeter(P) of a triangle is the total sum of the sides, in this case:

P = s + m + l

You know:

P = 26in

l = s + 3     [longest side is 3in longer/more than(addition) the shortest side]

m = s + 2   [medium side is 2in longer than the shortest side]

To find the lengths of the three sides, you can do this:

P = s + m + l         Substitute/plug in what you know. So plug in 26 into "P" since P = 26, plug in (s + 3) into "l" since l = s + 3, and plug in (s + 2) into "m" since m = s + 2

26 = s + (s + 2) + (s + 3)     Combine like terms (like terms have the same variable and power/exponent)

26 = 3s + 5   To find "s", isolate/get the variable "s" by itself. Subtract 5 on both sides

21 = 3s      Divide 3 on both sides to get "s" by itself

7 = s        

Now that you found s, you can use it to find the other sides

m = s + 2          Substitute/plug in 7 into "s" since s = 7

m = 7 + 2

m = 9

l = s + 3    Plug in 7 into "s"

l = 7 + 3

l = 10

The longest side is 10 inches, the medium side is 9 inches, the shortest side is 7 inches

PROOF

P = s + m + l

P = 7 + 9 + 10

P = 26 inches
