I assume you mean A = k^2 + 19k + 60. If the values of k are natural numbers then the area must be A = (k + 15)(k + 4) which is the factored form of the quadratic. The only statement about the rectangle that can be made is that the long side of the rectangle is 11 more than the short side. Lets say that k = 10 then the dimensions of the rectangle are 25 and 14.

What is the truth value for the following conditional statement?
Studentka2010 [4]

Answer:

TT→T

Step-by-step explanation:

If p is false, then ~p is true.

If q is false, then ~q is true.

Now note that

  • If a and b are both true, then a→b is true.
  • If a is true, b is false, then a→b is false.
  • If a is false, b is true, then a→b is true.
  • If a and b are both false, then a→b is true.

In your case, both~p and ~q are true, then ~p→~q is true too (or TT→T)

5p + 8 = 7p + 2 (Finding Common Denominators)
steposvetlana [31]
<span>Simplifying 7p + 2 = 5p + 8 Reorder the terms: 2 + 7p = 5p + 8 Reorder the terms: 2 + 7p = 8 + 5p Solving 2 + 7p = 8 + 5p Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-5p' to each side of the equation. 2 + 7p + -5p = 8 + 5p + -5p</span>

ABCDE ~ FGHIJ. Figure 2 is a dilation of figure 1, and the scale factor is 0.6. Given that FG = 12 cm, find AB.
avanturin [10]
We known that the figures are similar if and only if the corresponding sides and and angles have the common scale factor. In this item, the scale factor is 0.6. The length of AB is determined by multiplying the length of FG with the scale factor. That is,
                            AB = FG x scale factor
                            AB = (12 cm) x 0.6
                            AB = 7.2 cm
Thus, the length of side AB is 7.2 cm.
