Answer: 6^{2} - 19x + 15

Step-by-step explanation:

Expand

(2x−3)(3x−5)

using the FOIL Method.

2x(3x)+2x x -5 -3 (3x) -3 x -5

Simplify and combine like terms.

$6^{2} - 19x + 15$

Distribute:
2x(3x - 5) + 3(3x - 5)

6x^2 - 10x + 3(3x - 5)

6x^2 - 10x + 9x - 15

Combine Like Terms
6x^2 - x - 15

Solution
6x^2 - x - 15

2/3 gas tank cuts 3 lawns how many does 1 gas tank cut

postnew [5]

(2/3) / 3 = 1/x...2/3 to 3 lawns = 1 to x lawns
cross multiply
(2/3)(x) = (3)(1)
2/3x = 3
x = 3 * 3/2
x = 9/2 or 4 1/2 lawns can be cut with a full tank of gas

Answer:

Step-by-step explanation:

First do parenthesis:

3*(9+1)-6 -> 3*(10)-6

Then do multiplication:

3*(10)-6 -> (30)-6

Then complete it with subtraction:

(30)-6 -> (24)

So your answer would be 24!

I'M OFFERING 20 POINTS-

Dafna11 [192]

Answer:

Third option is correct. Scale factor 3 ; enlargement.

Step-by-step explanation:

It is given that the figure A'B'C'D' is a dilation of figure ABCD.

We know that after dilation the corresponding sides of image and preimage are in the same proportion.

The image of AD is A'D'.

From the figure it is noticed that the A(-1,2), D(-1,-1), A'(-3,6) and D'(-3,-3).

Distance formula is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$AD=\sqrt{(-1+1)^2+(-1-2)^2}=\sqrt{9}=3$

$A'D'=\sqrt{(-3+3)^2+(-3-6)^2}=\sqrt{81}=9$

Scale factor is constant which represents the relation between image and preimage.

$k=\frac{A'D'}{AD}$

$k=\frac{9}{3}$

$k=3$

Therefore the scale factor is 3.

If k>0 it means enlargement and if k<0 it means reduction. Therefore third option is correct.
