Answer:
x = 3
Step-by-step explanation:
2x+6=x+9 subtract x in both sides
x +6 =9 subtract 6 in both sides
x = 3
Answer:
The answer is option (B)
Here is the explanation...
Important: Use the symbol "^" to denote exponentiation:
<span>x3 – 9x2 + 5x – 45 NO
</span><span>x^3 – 9x^2 + 5x – 45 YES
Look at the first 2 terms. They can be rewritten as x^2(x-9). Then look at the last 2 terms. They can be rewritten as 5(x-9). So, x-9 is the common factor here. Thus, the original expression becomes:
(x^2-5)(x-9).
Note that x^2-5 can be factored, so that the final 3 factors are:
(x-sqrt(5)), (x+sqrt(5)), (x-9).</span>
Answer:
1 cm to 7.5 m
Step-by-step explanation:
A drawing scale is a ratio of two numbers.
The given scale, 4 cm to 30 m, can be written as a ratio in the form of a fraction,
(4 cm)/(30 m)
Since it can be written as a fraction, it can also be reduced like a fraction.
The problem wants the number of cm to be 1 cm. We have 4 cm.
Divide the numerator and denominator by 4.
(1 cm)/(7.5 m)
Now write it in the format the problem asks.
1 cm to 7.5 m
