Find the x-intercepts for the parabola defined by the equation below. y = x2 + x - 12

1 answer:

7 0

<span>The parabola intercepts the x-axis happen when? Well, it's when "y" = 0. So you want to solve for x, 0 = 2x^2 + 2x -4</span>

The perimeter of a rectangle is 38 units. The length is 13 units longer than the width. What are the dimensions of the rectangle

s2008m [1.1K]

Answer:

Step-by-step explanation:

P = 2(l +w)

Let width be x

Length = x + 13

P = 38

38 = 2(x + 13 + x)

38 = 2(2x + 13)

38 = 2x + 26

2x = 38 - 26

2x = 12

x = 12/2

x = 6unit

Width = 6units

Length = x + 13 = 6+13 = 19units

Oh god does anyone understand this? I need help it’s for a test and I wanna do good!!

Kobotan [32]

Answer:

Step-by-step explanation:

Its a right angle, so you have to use trigonometry.

To find x , you use sin60° = opposite/hypotenuse

opposite = x and hypotenuse = 5 . So,

sin60°= x/ 5

5sin60° = x

put the value into your calculator you ' ll get:

$x = \frac{5 \sqrt{3} }{2}$

To find y, cos60°= adjacent/hypotenuse

adjacent= y and hypotenuse = 5. So,

cos60°= y/5

5cos60°=y

$y = \frac{5}{2}$

Hope I was able to help. Good luck!<3
