Answer:
x = 12
Step-by-step explanation:
3 (x-5) = 2x - 3
3x -15 = 2x - 3
x-15 = -3
x = 12
check:
21 = 21
Answer:
309^2 - 147^2 is the same as 95,481 - 21,609.
95,481 - 21,609 = 73,872.
Prime Factors of 73,872 =2, 2, 2, 2, 3, 3, 3, 3, 3, 19
Which is the same as = 24 x 35 x 19
The first one is less and the seccond one is above
Answer:
Step-by-step explanation:
y = x/4 - 12
x = y/4 - 12
y/4 - 12 =x
y/4 = x + 12
y = 4x + 48
h(x) = 4x + 48
y = 3x - 122
x = 3y - 122
3y - 122 = x
3y = x + 122
y = x/3 + 122/3
f^-1(x) = x/3 + 122/3
