Can someone explain what to do
castortr0y [4]

Answer:

8

Step-by-step explanation:

The equation of the parabola can be represented as

y = a(x + 1)(x - 5)

for some constant a.

Since the coefficient of x² is 2, a = 2, so

y = 2(x  + 1)(x - 5) \\  \\ y = 2( {x}^{2}  - 4x + 5) \\  \\ y = 2 {x}^{2}  - 8x + 10

So, the answer is 8.

A rectangular parking lot has an area of 682 square yards.The lot is 22 yards wide.What is the length of the parking lot?
postnew [5]

Answer:

Area of rectangle with length 'l' and width 'w' = l \times w

The area of rectangular parking lot = 682 square yards.

The width of the rectangular parking lot = 22 yards

Let the length of the rectangular parking lot be 'x' yards.

Since, area of rectangular parking lot = l \times w

682 = x \times 22

So, x=\frac{682}{22}

x=31 yards

Therefore, the length of the rectangular parking lot is 31 yards.

Simplify (3x + 5) + (2x - 9) - (4x + 3).<br><br> x - 7<br> -x - 7<br> -9x - 1<br> 9x - 1
Lyrx [107]
Hi Grant.

(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.

3x + 2x; 5 - 9; we result with: 5x - 4

Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.

(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.

5x - 4x; -4 - 3; we result with x - 7.

Your answer is A.) x - 7.

I hope this helps!
