Answer:
{-3, -1, 1}
Step-by-step explanation:
Zeros refer to x-intercepts. X-intercepts are x values when y = 0. You can tell where they are by looking at where the line passes the x-axis.
Therefore, {-3, -1, 1} are the zeros.

Answer:
diagonal is 11.14 cm
Step-by-step explanation:
We start by writing the equation for the width (w) in terms of the length (L):
w = 2 L - 8
from the area = w * L = 62
we replace w in it: w * L = (2 L -8) * L = 62
2 L^2 - 8 L = 62
2 L^2 - 8 L - 62 = 0
extract 2 common factor:
2 (L^2 - 4 L - 31) = 0
Using quadratic formula we get:
[tex]L=\frac{4+/-\sqrt{4^2-4(1)(-31)} }{2} \\L=\frac{4+/-\sqrt{140} }{2}\\L=7.916\\or\\L=-3.916[/tex]
So, we pick the positive answer L = 7.916 cm
Then we now know the with of the rectangle as well:
w = 2 * L - 8 = 2 * 7.916 - 8 = 7.832 cm
Now we estimate the diagonal of the rectangle using the Pythagorean theorem:
[tex]diag=\sqrt{7.916^2+7.832^2}\approx11.1356\,\,cm[/tex]
which rounded to two decimal places is 11.14 cm

(a) If a package of curtains cost $21.50, what is the cost of the 3 packages of curtains in the cart?
(b) If a gallon of paint costs $7.96, what is the cost of the 3 gallons of paint in the cart?
(c) If a lamp shade costs $14.99, what is the cost of the 3 lamp shades in the cart?
(d) Find the total cost of all the items in the cart. Then, find the amount of money the family has left, if any, from the $400.

Measures of two anges 48 degrees are shown in a triangle. Write a equation showing the value of X
Answers
Answer:84
Step-by-step explanation:
Since each trinagle's interior angles which is the angles in side the triangle always add up to 180 you could add the 2 given and then subtract by 180 so 48+48 which equals 96 then 180-96 which will give you 84 as x
Answer
48+48+x=180 x=84
Step-by-step explanation:
The sum of the 3 interior angles of a triangle is always the sum of 180 degrees.
In short, this means that all three angles have to equal up to 180 degrees
48+48=96
180-96=84 x=84
To check your answer add
48+48+84 should equal 180. It does
