We can use the Front Outside Inside Last (FOIL) method to expand the double bracket

$(3x+5)(5x-1)$

Front ⇒ $(3x)(5x)=15 x^{2}$
Outside ⇒ $(3x)(-1)=-3x$
Inside ⇒ $(5)(5x)=25x$
Last ⇒ $(5)(-1)=-5$

Put the four terms together we have
$15 x^{2} -3x+25x-5$ , then collect like terms
$15 x^{2} +22x-5$

oksian1 [2.3K]

Answer:

37.6%

Step-by-step explanation:

P(A|B) = P(A and B) / P(B)

P(red | car) = P(red and car) / P(car)

P(red | car) = 0.32 / 0.85

P(red | car) = 0.376

plsss helppp need it fastt .. what is the volume of this figure answer your answer in the box . 4ft 3ft 8ft 2ft 6ft

PolarNik [594]

Answer:

Step-by-step explanation:

The cube on the top, the one with the width of 4 is Cube 1.

The other one is Cube 2.

The length of the cube is 4, the width 2, and the height 5.

We know the length is 4 because we can look at the side, where both measurements 6 ft and 3 ft can be found.

We know that the height is 5 because for Cube 2, the height is 3. The total height is 8, so we subtract 3 from 8. We get our difference of 5.

V = l x w x h

V = (4)(2)(5)

V = (8)(5)

V = 40.

Cube 2 has a length is 6, the width 2, and the height 3.

V = l x w x h

V = (6)(2)(3)

V = (12)(3)

V = 36

We add the volumes of both cubes.

40 + 36 = 76

probs not right but hope it helped :)

Mama L [17]

Answer: (12,9), (6,9), (12,-6) and (6,-6)

Step-by-step explanation:

Given: The coordinates of the original rectangle are (8, 6), (4, 6), (8, −4), and (4, −4). We know that the coordinates of the image after dilation from the origin by a scale factor of k is given by:_
