Answer:
14 or -22
Step-by-step explanation:
st=18
s=-4
-4+18=14
so t can be at 14
or -4-18=-22
t can be at -22
Step-by-step explanation:
3/8 = 15/40= 75/200
2/5 = 16/40 = 80/200
-> 4 rational numbers between 75/200 and 80/200 are 76/200, 77/200, 78/200, 79/200
Step-by-step explanation:
(i)
-2/5 = -4/10 = -6/15 = -8/20
(ii)
3/7 = 6/14 = 9/21 = 12/28
we simply multiply top and bottom (numerator and denominator) by the same number.
Answer:
(2x - 3a³) ,(2x + 3a³)
Step-by-step explanation:
Given that
4x^2-9a^6
As we know that
x² - y² = ( x+y)(x-y)
So
4x^2-9a^6 = (2x)² - (3a³)²
By using the above formula
x² - y² = ( x+y)(x-y)
4x^2-9a^6 = (2x)² - (3a³)²
4x^2-9a^6 = (2x - 3a³) (2x + 3a³)
So the factor is (2x - 3a³) ,(2x + 3a³)
To verify
Multiple both factors
(2x - 3a³) (2x + 3a³) = 2x .2x -2x . 3a³ + 3a³ . 2x - 3a³. 3a³
=4x² - 9 a ⁶
