14=3(x-2)+5<br>How can I solve this equation?​
daser333 [38]
1. distribute the 3 into the variable and number in the equation
to do this..
2. multiply 3 by x (obtain the answer of 3x)
3. multiply 3 by -2 (obtain the answer of -6)
4. you now have the equation of ‘14 = 3x-6+5’
5. subtract 6 from 5 (obtain the answer of -1)
6. you now have the equation of ‘14 = 3x-1’
7. add one to both sides (cancel out the negative one and make the opposite side of the equation 15 instead of 14)
8. you now have the equation of ‘15 = 3x’
9. divide both sides by 3 (15 and x)
FINAL ANSWER
x = 5
hope this helps:)

Please help me guys ​

Answer:

Example 11 answer = 12

Step-by-step explanation:

40, 36, 32, 28

is an arithmetic sequence.

The first term (a) is 40

The common difference (d) is -4

The formula for finding the nth term (X_{n} in an arithmetic sequence is;

X_{n} = a + d(n - 1)

X_{8} = 40 + -4(8 - 1)

X_{8} = 40 - 28 = 12

Is this right? Or is the answer B?
baherus [9]

For this case we must find an expression equivalent to:

\sqrt [4] {f}

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So, rewriting the given expression we have:

f ^ {\frac {1} {4}}

Answer:

Option 1
