Matthew is 7 years older than twice the age of his sister. If Matthew is 13, how old is his sister?
Iteru [2.4K]
Let sister be s.  Matthew, M

Matthew is 7years older than twice the age of his sister

M = 7 + 2s

13 = 7 + 2s.   7 crosses the equality to other side and becomes -7

13 - 7 = 2s

6 = 2s    Divide both sides by 2

6/2 = 2s/2

3 = s

Sister is 3 years old.

What is the simplified form of 5 square root x^4 • 5 square root x^4
laiz [17]

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

\sqrt[5]{x^4} becomes x^4^/^5

When you multiply 2 terms with the same base, you add the exponents.

x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5

x^8^/^5 is also the same as x\sqrt[5]{x^3}

You get this because \sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}. When you pull out 5 os x, you are left with x³ on the inside.
