It is 4:2
Since it is similar AB is double the size of AB' and BC is double the size of BC'. so 4:2 4 is double the size of 2.
ANSWER
EXPLANATION
The given equation is
Recall that
Apply this rule on the right hand side to get,
Express both sides to base 3.
Equate the exponents:
3(1-x)=2(-2x)
Expand:
Group like terms,
Answer:
Step-by-step explanation:
Since both fractions have a different denominator, we need to look for a common denominator.
Multiply 3 in both numerator and denominator
Hence, 2/9 is the answer
First step (7x2 - 16x) - 8 = 0
Second step Factoring 7x2-16x-8
The first term is, 7x2 its coefficient is 7 .
The middle term is, -16x its coefficient is -16 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 7 • -8 = -56
Step-2 : Find two factors of -56 whose sum equals the coefficient of the middle term, which is -16 .
All of that said it’ll be 2.708
How I got 2.708 is x =(16+√480)/14=(8+2√ 30 )/7= 2.708
And 0.422 is x =(16-√480)/14=(8-2√ 30 )/7= -0.422
1/10 of 3000 is simply dividing
3000/10=300
