Is the expression 4(3 + 5) – 10 = 4 x 3 + 5 – 10 true or false? Explain

1 answer:

6 0

False.

For the first part, 4(3 + 5) needs to be added first so its 4 * 8. This is 32 - 10.

The second part will have 4 * 3 which is 12 + 5 which is 17. Finally subtract 10 and its 7.

And 22 is not equal to 7

What is the length of BC? If your answer is not an integer, leave it in simplest radical form?

nexus9112 [7]

ANSWER

$|BC|=12\sqrt{2}\: ft$

EXPLANATION

The given right triangle is an isosceles triangle because

$m \: < \: B = 45 \degree = m \: < \: C$
This implies that,

$|AB|=12ft=|AC|$

From the Pythagoras Theorem,

$|BC|^2=|AB|^2+|AC|^2$

$|BC|^2= {12}^{2} + {12}^{2}$

$|BC|^2=2 \times {12}^{2}$

$|BC| = \sqrt{ {12}^{2} \times 2 }$

$|BC|=12\sqrt{2}\: ft$
