Answer:
So, y = 2x + 7;
Then, 2x = 4( 2x + 7 ) - 16;
2x = 8x + 28 - 16;
2x = 8x + 12;
- 6x = 12;
x = - 2;
Then, y = 2· (-2) + 7;
y = - 4 + 7;
y = 3.
Step-by-step explanation:
A(20) = a+(20-1)d
A(20) = 102+(19)(-3)
A(20) = 102-57 = 45
Option D
a+3b=8
Yes.
You are correct except to the nearest hundredth it is 795.54 cm^2.
False. That does not satify the equation
