The side length 9sps behave. S s. Shahebgshehzgbzbh eugenics
sum means addition, so just add the three numbers...
12.6 +3.1 = 15.7 + 5.4 =21.1
21.1 is greater than 20
Answer:
x = - 8, x = 6
Step-by-step explanation:
Given
(x - 6)(x + 8) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 8 = 0 ⇒ x = - 8
Answer:
A. {(0, 3), (1, 6), (2, 9)}
Step-by-step explanation:
All you have to do is substitute them
A.
y − 3 = 3x
3 - 3 = 3 (0)
0 = 0
y − 3 = 3x
6 - 3 = 3 (1)
3 = 3
y - 3 = 3x
9 - 3 = 3 (2)
6 = 6
__________________________________________________________
B.
y - 3 = 3x
0 - 3 = 3(3)
-3 = 6
You can tell that this one can't be one of the answer which means that B wont be the answer, so you don't have to do anymore work for this one.
__________________________________________________________
C.
y - 3 = 3x
3 - 3 = 3(1)
0 = 3
This one can't be an answer either
__________________________________________________________
D.
y - 3 = 3x
1 - 3 = 3(1)
-2 = 3
And this one can't be an answer either
__________________________________________________________
This concludes, that A will be the answer here since all of the ordered pair can be x and y when you use the inputs and outputs that were given.
Hope this helped!
Answer:
The answer is: The largest number is 15.
Step-by-step explanation:
Let n = the number
n + (n + 1) + (n + 2) + (n + 3) = (n + 4) + (n + 5) + (n + 6)
4n + 6 = 3n + 15
n = 9
Proof:
9 + 10 + 11 + 12 = 19 + 23 = 42
13 + 14 + 15 = 27 + 15 = 42
Hope this helps! Have an Awesome Day!! :-)
