S=S1+S2, where S1=12*4=48 cm², S2=0.5*(12-3-3)*(8-4)=12 cm².
S=48+12=60 cm²
I believe the answer is 9
This is because in order to take out a three, There would need to be 2 3's and 9 is 3x3, so the answer is 9.
Answer:
No real solutions.
Step-by-step explanation:
x² + 6x + 10 = 0
a = 1
b = 6
c = 10
D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4
- 4 < 0,
so this equation has no real solutions.
