Answer:
-16
Step-by-step explanation:
-k² -(3k-5n)+4n k=-1 , n= -2
= -(-1)² - ( 3(-1) -5(-2) )+4(-2)
= -1-(-3+10)-8
= -1-(7)-8
= -1-7-8
= -16
You first multiply the outside exponents into the numbers in the parentheses.
When you have an exponent being multiplied directly to another exponent, you multiply the exponents together.
For example(because I am a bad explainer):
When you divide an exponent by an exponent, you subtract the exponents
For example:
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:
You can think of it like this if you want:
Now multiply the outside exponents into the exponents in the parentheses
Divide 27 and 9

Answer :
The value of q for, the given quadratic equation is 40
Step-by-step explanation :
Given quadratic equation as :
x² - 14 x + q = 0
And , Difference between the roots of equation is 6
Let A , B be the roots of the equation
So, A - B = 6
The roots of the quadratic equation ax² + bx + c = 0 as can be find as :
x =
x =
or, x =
Or, x =
So , The roots are
A =
And B =
∵ The difference between the roots is 6
So, A - B = 6
Or, ( ) - ( ) = 6
Or, ( - 7 + 7 ) + 2 ( = 6
Or, 0 + 2 ( = 6
∴ 196 - 4 q = 36
or, 4 q = 196 - 36
or 4 q = 160
∴ q =
I.e q = 40
S0, The value of q = 40
Hence The value of q for, the given quadratic equation is 40 . Answer

Answer:
3/8 ÷ 5/12 can be written as
3/8 × 12/5
so,
3/2 × 3/5
9/10
hence the quotient is
