Answer: First question: D, Second question: A
Step-by-step explanation:
Note: I'm not so good at expanding so I'll just solve it :)
So this leaves either C or D
Apply the sum rule:
8-70=-62
The only one that gives a negative sum is D
For the second picture, the one you have chosen is correct
a1 = 3 and r = -5 so:
an = 3/5 * (-5)^n
Plugging in 8 for n (the first choice) we get the given term: -234,375
 
        
                    
             
        
        
        
About $801.99 bc 603X.33 is 198.99 plus 603 is 801.99

Answer:
Below.
Step-by-step explanation:
The dimensions will be 10 * 12.
(each new dimension will be 4 times the original)
The new perimeter will be 4 times the original.
The new area will be 16 times the original ( 4 * 4 = 16).
The new perimeter will be 44 cm.
