Find the amount of change by subtracting the two quantities. Divide this number by the original (starting) quantity, and convert to percent form by moving the decimal 2 places to the right.
Answer:
5 + 2
Step-by-step explanation:
Multiply top and bottom by sqrt(3) + sqrt(2)
Top = (sqrt (3) + sqrt(2)) * (sqrt(3) + sqrt(2))
Top = 3 + sqrt(6) + sqrt(6) + 2
Top = 5 + 2sqrt(6)
Bottom = (sqrt (3) - sqrt(2)) * (sqrt(3) + sqrt(2))
Bottom = (3 - sqrt(6) + sqrt(6) - 2)
Bottom = 1
So, the answer is 5 + 2
Answer:
B & C
Step-by-step explanation:
Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.
A-(5)(0.6)*7=21
B-(4/5)(15)+8=(0.8)(15)+8=20
C-4(8+2)/2=4(10)/2=40/2=20
D-14+4(2+3)=14+4(5)=14+20=34
If you need any clarification just lmk :)
