Since it is on the graph, you know that the factored form gives you the roots. If you look at the graph, the x intercepts are the roots. So x=-2, x=-1, and x=3. That means factored form would be (x+2)(x+1)(x-3)

That’s choice D!

The roots of the equation are:x = -2, -1 and +3Therefore, the factored equation should have the opposite signs:(x +2) * (x +1) * (x -3)

Triangle A B C is cut by line segment S T. Line segment S T goes from side A B to side C B. Lines S T and A C are parallel. The
maksim [4K]

Answer:

Option C.

Step-by-step explanation:

Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.

Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.

Using triangle proportionality theorem we get

\dfrac{SA}{SB}=\dfrac{CT}{BT}

\dfrac{SA}{10}=\dfrac{2.7}{9}

On cross multiplication we get

9\times SA=2.7\times 10

9SA=27

Divide both sides by 9.

SA=3

The length of SA is 3ft.

Therefore, the correct option is C.

Zack wanted to build a fenced in area for a dog kennel in his backyard. The fenced in space has a length of 5 1/4 feet and a wid
Radda [10]

Answer:

Zack will need 17 1/2 ft of fence

Step-by-step explanation:

To calculate this we will first pass the numbers to complete fractions

5 1/4 ft = 21/4 ft

3 1/2 ft = 7/2 ft

We have to add 2 times each side

21/4 ft + 21/4 ft  + 7/2 ft + 7/2 ft =

Now we have to pass all the fractions to the same denominator

21/4 ft + 21/4 ft  + 14/4 ft + 14/4 ft  =

70/4 = 17 1/2

Zack will need 17 1/2 ft of fence
