Answer:

Step-by-step explanation:
15mph because you take 70-55 and you get 15mph
Answer:
21w+3
Step-by-step explanation:
5w+9w+5+7w-2
14w+5+7w-2
21w+3
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Answer:
Option d) is correct
ie, quotient property
Step-by-step explanation:
Given expression is log 618-log 66=log 63
Now we take log 618-log 66
log 618-log 66 = log
[By using quotient property, log
]
= log 63
Therefore log 618- log 66= log 63
Option d) is correct
In the given expression we are using the quotient property
