Answer:

\overline {AD} = 5

Step-by-step explanation:

From the given diagram we are required to find the length of \overline {AD}

The given parameters are;

ΔABC and ΔCDA are congruent

The length of \overline {BC} = 5

The length of \overline {AC} = 7

The length of \overline {CD} = 4

From ΔABC ≅ ΔCDA, we have;

\overline {AC} = \overline {AC}  By reflexive property

∴ \overline {BC} = 5 is either equal to \overline {AD} or \overline {CD}

However, \overline {CD} = 4, therefore, \overline {BC} ≠ \overline {CD}

We can then have;

\overline {BC} = \overline {AD} = 5.

How can this product be simplified 8p(-2p^2+6p-2)
Nikitich [7]

Answer:

-16p³ + 48p² - 16p

Explanation:

In order to simplify the given expression, we need to multiplied 8p with (-2p²+6p-2)

8p*(-2p²+6p-2)

we need to distribute 8p over the brackets or parenthesis.

=8p*(-2p²) + 8p*(6p) + 8p*(-2)

= 8*(-2)*p*p² + 8*6p*p + 8*(-2)* p

= -16p³ + 48p² - 16p

We can't simplify it more, so that's the final answer.

I hope it's help.
