Answer:
The values of k are 2/3 and -1
Step-by-step explanation:
Product of zeros = αβ= constant / coefficient of x^2 = 4/k
Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k
Given
Consider a= α and b= β

can be written as
if we add
in the above equation.


Putting values of αβ and α+β

The values of k are 2/3 and -1
-27 minus 10 isn't -17....its -37 so since that mistake everything else is counted as a mistake
Hope this helps
Answer:
She has 16 brownies
Step-by-step explanation:
Initially cut rectangular pan in to two halves.
Then cut each half in half again.
Now total pieces = 4
Now repeat cutting half on other side:
total pieces =8
Now divide each half into another half.
total pieces = 8 x 2 = 16
As can be shown in figure:
Black = first half
pink = dividing each half into another half.
1. Commutative property of multiplication
IM SO SORRY IF IM WRONG
Answer: x = 11
To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.
Now, write the equation: 122 = 13x - 21
Solve this, to find the x = 11.
