Answer 1

Answer:

The possible dimensions are -7 and -8 units.

Solution:

Area of the rectangular skateboard park = $x^(2)+15 x+56$

To find the dimensions of the park.

Let us factor the polynomial:

$x^(2)+15 x+56=0$

15x can be written as 7x + 8x.

$x^(2)+7 x+8x+56=0$

$(x^(2)+7 x)+(8x+56)=0$

Take x common in 1st two terms and 8 common in next two terms.

$x(x+7 )+8(x+7)=0$

Make sure that the remaining terms in the bracket should be equal.

Now, take the common term (x + 7) outside from both terms.

$(x+7)(x+8)=0$

$x+7=0 \ \text{or} \ x + 8 = 0$

$x=-7 \ \text{or} \ x = -8$

If the length of the park is -7 then the width is -8.

If the length of the park is -8 then the width is -7.

The possible dimensions are -7 and -8 units.

Equation of perpendicular line:

Equation of parallel line:

Answers

1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.

To find the y-intercept, solve for "b".

b=-7/3

Our equation would then be y=2/3x-7/3

2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.

b=-11

So our perpendicular equation would be y=-3/2x-11

given a rectangle of length a and width b if A and B are both rational numbers would the perimeter be irrational or rational? Give an example choosing your own values for a and b

Answers

The perimeter would be rational due to both the width and length being rational numbers. A rational number is a number that can be written as a fraction such as 8 it can be written as 8/1, but a irrational would be a decimal number which in this case there would be none because both length and width is rational number. For example, Lets say the width is 8 and the length is 10. once both are written into fraction form such as 8/1 and 10/1 we add them to get a perimeter of 18.
