You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5
Answer:
-96
Step-by-step explanation:
In order to get the opposite of an integer, you just need to change its signal. So, the opposite of 96 is -96. If you add the opposite or additive inverse of the number to the number itself the result will be 0.
So, 96 plus -96 = zero.
H (x) = 5 x 2^-x
2^-x is the same as saying 1/2^x .
h (x) = 5 x 1/2^x
h (3) = 5 x 1/2^3
= 5 x 1/8
= 5/8
Therefore h (3) = 5/8
Answer:
1930g
Step-by-step explanation:
Mass = density × volume
