Answer:
answer is D
Step-by-step explanation:
as we need to cancel the square in b
so we add square root on both sides and square root of 2.56 is 1.6
C and D
Given
b² = 2.56 ( take the square root of both sides )
b = ± = ± 1.6
Then solutions are
b = - 1.6 → C
b = 1.6 → D
x=4 y=7
When multiplying 3x by -2, you get -6x. -6x and 6x cross out. You're left with -2y=-2 and -2y=10.
