The correct answer would be 21 feet, as the image shown is an equilateral triangle. Thus, finding the perimeter we add up all sides and get the answer of 21 feet, which is less than 28 feet as needed.
2x - 5 = 7
2x = 7 + 5
2x = 12
2x/2 = 12/2
x = 6
to check:
2x - 5 = 7
2(6) - 5 = 7
12 - 5 = 7
7 = 7
Answer:
Because D = 24 and this is bigger then zero, there are two real solutions.
Step-by-step explanation:
if the discriminant (D) has a positive number, then there are two real solutions. So let's calculate the value of D.
-2x² + 3 = 0
a = -2
b = 0
c = 3
D = b² - 4 * a * c
Substitute the values of a, b and c and you get...
D = 0² - 4 * -2 * 3
D = 24
Because D = 24 and this is bigger then zero, there are two real solutions.
Answer:
The price per pound of gummy bears is $3.20 and the price per pound of jelly beans is $7.50
Step-by-step explanation:
Let
x ----> the price per pound of gummy bears
y ----> the price per pound of jelly beans
we know that
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (3.2,7.5)
see the attached figure
therefore
The price per pound of gummy bears is $3.20 and the price per pound of jelly beans is $7.50
