4 0
STEP-BY-STEP SOLUTION:

0 = ( 5x + 13 ) ( 3x + 7 )

0 = 15x^2 + 35x + 39x + 91

0 = 5x ( 3x + 7 ) + 13 ( 3x + 7 )

0 = ( 3x + 7 ) ( 5x + 13 )


3x + 7 = 0

3x = - 7

x = - 7 / 3


5x + 13 = 0

5x = - 13

x = - 13 / 5


ANSWER:

Therefore, there are two solutions to this problem. The answer is:

x = - 7 / 3

&

x = - 13 / 5

Marysya12 [62]

Answer:

g(x)=(x+4)^2-5

Step-by-step explanation:

g(x) is shifted 5 down in the y axis, meaning you have to subtract 5 from the function, and is shifted 4 to the left in the x axis- meaning you have to add to the x's in the function.

What is "The relationship between time and the distance Remaining on a 3 mile walk for someone walking at a steady rate of 2 mph
FromTheMoon [43]

Answer:

Let d be the remaining distance.

Let t be the remaining time.

The standard distance equation is:

d = rt

We are given the rate as 2, so:

d = 2t

At the start of the walk, the remaining distance is 3 miles.

The remaining time is 1.5 hours.

At the end of the walk, the remaining distance is 0 miles.

The remaining time is 0 hours.

A graph of the distance and time would be a continuous, solid line. That's because the walker will be at every distance between 3 and 0 and every time between 1.5 and 0.

Answer:

The graph of this would be a solid line

The base of the 37 foot ladder is 9 feet from the wall of a building. will the top of the ladder reach a window ledge 35 feet ab
AnnZ [28]

Answer:

The answer to your question is Yes.

Step-by-step explanation:

The math in this problem is that we need to use the Pythagorean theorem to solve it. Pythagorean theorem is part of trigonometry a branch of Maths.

Data

base = 9 ft                      

length = 37 ft

height = ?

Pythagorean theorem

                                     c² = a² + b²

length = c

base = a

height = b

                                   37² = 9² + b²

-Solve for b

                                    b² = 37² - 9²

-Simplify

                                    b² = 1369 - 81

                                    b² = 1288

-Result

                                   b = 35.88

-Conclusion

The ladder will reach a height higher than 35 ft.
