Mathematics
1 answer:
Mariana [72]3 years ago
5 0

Answer:

Negative

Step-by-step explanation:

Years of Factoring:

What the problem tells us is that we have:

X^2 - 4x - 3

or something along these lines. If we factor this we get:

(X-4)(X+1)

The bigger inside factor has to be negative for these problems, because the third term is negative.

Mario is setting up a new tent during a camping trip . The tent came with 7 feet of rope . The instructions are to use 34.5 inch
andrezito [222]

Answer:

The number of  8\frac{1}{4}  inch sections of a rope Mario can cut from the rope is <u>6</u>.

Step-by-step explanation:

Given:

Mario is setting up a new tent during a camping trip . The tent came with 7 feet of rope . The instructions are to use 34.5 inches of the rope to a tie the tent stakes in the ground . Mario will use all of the rope as instructed

Now, to write and solve equation to determine the number of 8 1/4 inch sections of a rope Mario can cut from the rope.

Let the number of sections be x.

The length of rope Mario can cut from the rope = 8\frac{1}{4} =\frac{33}{4} \ inch.

<em>Total length of rope = 7 feet.</em>

So, 1 feet = 12 inches.

<em>Thus, the length of rope in inches = 7 × 12 = 84 inches.</em>

The length of rope to tie the tent stakes in the ground = 34.5 inches.

According to question:

Now, to get the number of sections we put an equation:

x\frac{33}{4} =(84-34.5)

x\times \frac{33}{4} =49.5

x\times 8.25=49.5

<em>Dividing both sides by  8.25  we get:</em>

x=\frac{49.5}{8.25}

x=6.

<em>The number of sections = 6.</em>

Therefore, the number of  8\frac{1}{4}  inch sections of a rope Mario can cut from the rope is 6.
