The width and length of a rectangle (in feet)are consecutive odd integers. If the length is increased by 5 feet, the area of the

Tresset [83]

Original:
<span>The width and length of a rectangle are consecutive odd integers
</span>so W = x and L = x + 2

<span>If the length is increased by 5 feet, then new L = x + 2 + 5 = x + 7
</span>
A = L x W
60 = (x + 7) x
60 = x^2 + 7x
x^2 + 7x - 60 = 0
(x - 5)(x + 12) = 0
x = 5 and x = -12

From here you have x = W = 5 ft and L = x + 2 = 5 + 2 = 7 feet

Area of original = 5 x 7 = 35

answer
<span>the area of the original rectangle: </span>35 ft^2

Mark is going to an awards dinner and wants to dress appropriately. He is running behind schedule and asks his little brother to

Cerrena [4.2K]

Answer:

The answer is " $\bold{\frac{2}{3}}$ ".

Step-by-step explanation:

Pick a shirt first: 3 choices

Pick slacks next: 2 choices

Then choose a tie: 1 choice

Total: $3 \times 2 \times 1 = 6$ outfits.

These will be similarly divided between the two slacks, so 3 black slack outfits of $6 = \frac{1}{2}$ . Similarly, the 6 styles are also divided between the option of 3 shirts. 2 blue shirt outfits $6 = \frac{1}{3}$

To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add $\frac{1}{2} \ and \ \frac{1}{3}$ . Add $\frac{1}{2} \ and \ \frac{1}{3}$ , and remove the chance for both the black slack shirt and outfit and are one of the six outfits:

$\to \frac{1}{2} + \frac{1}{3} -\frac{1}{6} =\frac{3+2-1}{6} =\frac{4}{6} = \frac{2}{3}$

Which of the following correctly classifies the number -5 to all of the number sets in which it belongs?

valina [46]

<h3>Answer: Choice C) Real, Rational</h3>

=============================================

Explanation:

Any number you'll encounter so far in your math course will be a real number. This is until you get to something like $\sqrt{-1}$ which is a complex number, but your teacher may not have covered that chapter yet.

Anyways, -5 is a real number because we aren't taking the square root of a negative or anything like that.

-5 is also an integer, but that choice isn't listed. The set of integers is any positive or negative whole numbers, including 0 as well.

Furthermore, -5 is considered rational because -5 = -5/1. We can write -5 as a fraction of two integers where 0 is not in the denominator. With -5 being rational, it cannot be irrational. The term "irrational" means "not rational".
