The perimeter of a triangle is the sum of its sides. So, we have
We have an exact value for the perimeter, and variable expressions for the sides. Let's substitute the formula above with what we're given:
If you divide both sides by 12, you have
So, the lengths of the sides are
Answer:
Option D (4, -5)
Step-by-step explanation:
This question can be solved by various methods. I will be using the hit and trial method. I will plug in all the options in the both the given equations and see if they balance simultaneously.
Checking Option 1 by plugging (-4, -5) in the first equation:
-2(-4) + 6(-5) = -38 implies 8 - 30 = -38 (not true).
Checking Option 2 by plugging (-5, 4) in the first equation:
-2(-5) + 6(4) = -38 implies 10 + 24 = -38 (not true).
Checking Option 3 by plugging (1, -6) in the second equation:
3(1) - 4(-6) = 32 implies 3 + 24 = 32 (not true).
Since all the options except Option 4 have been ruled out, therefore, (4,-5) is the correct answer!!!
option : c. 2x + 15 = 145
cuz, the angles are vertical opposite angles
Answer:
Step-by-step explanation:
A company claims that its soup vending machines deliver exactly 8 ounces of soup to every customer.
This means that the null hypothesis is that the mean is exactly 8, that is:
You do not want the vending machines to deliver too much or too little soup.
We don't want the mean to be different from 8, which means that the alternative hypothesis is given by:
Answer:n = 6
n, = 6
n = 0
n, = 0
n = 4
n, = 4
n = 2
n, = 2
Step-by-step explanation:n = 6
n, = 6
n = 0
n, = 0
n = 4
n, = 4
n = 2
n, = 2 equal to yz7 (*970
