Answer:
B and D.
Step-by-step explanation:
B. The numerator = 2*1 = 2 and x^4 - y^4 = (x^2 - y^2)(x^2 + y^2).
D . (x^2)^2 - (y^2)^2 = x^4 - y^4.
Answer: She should budget $672.89 monthly next year for this service.
Step-by-step explanation:
Since we have given that
Amount he was able to save per month = $48.50
Total amount he spent for the year = $1254.89
Amount he saved for the year would be
Amount left from total would be
Hence, She should budget $672.89 monthly next year for this service.
Answer:
-15
Step-by-step explanation:
6.8(6.7 – 7.2) – 2(4.6 + 1.2)
The first step in PEMDAS is to do whatever's in the parenthesis. So, this would be the 6.8 bit.
6.8 times 6.7 is 45.56 and then 6.8 times 7.2 which is 48,96
Now we can also do the second set of parenthesis. 2 times 4.6 is 9.2, and 2 times 1.2 is 2.4
The equation now reads- (45.56 - 48.96) - (9.2 + 2.4)
All we have to do is evaluate what's in the parenthesis, the first set equals -3.4 and the second set equals 11.6
So, now our expression reads, -3.4 minus 11.6 which equals -15
The answer is 16.27 rounded to the nearest hundredth
