Find the value of t in the diagram

12345 [234]

In a trapezoid, with bases $b$ and $B$ and height $h$ , the area is given by

$A = \frac{(B+b)h}{2}$

In your case:

$B = BC = 3t$

$b = AD = t$

$h = AB = t$

so, the formula becomes

$A = \frac{(3t+t)t}{2} = \frac{4t^2}{2} = 2t^2$

Since the area is $50 \text{cm}^2$ , we have

$2t^2 = 50 \iff t^2 = 25 \iff t = 5$

HELP!!! I need help in simplifying this question.

Answer: $x^{-4}=\frac{1}{x^{4}}$

Step-by-step explanation:

We have the following expression:

$(\sqrt[3]{x^{2}} \sqrt[6]{x^{4}})^{-3}$

Which can also be written as:

$(x^{\frac{2}{3}} x^{\frac{4}{6}})^{-3}$

Since we have exponents with the same base $x$ inside the parenthesis, we can sum both exponents:

$(x^{\frac{4}{3}})^{-3}$

Now, we have to multiply the exponent out of the parenthesis with the inner exponent and have the following result:

$x^{-4}=\frac{1}{x^{4}}$
