A = b = 12 cm

<span>Pythagorean theorem
</span>
$a^2+b^2=c^2\\\\ c^2=a^2+a^2\\\\ c^2=2a^2\\\\ c=\sqrt{2a^2}$

$c=a\sqrt2$ formula

$c=12\sqrt{2} \ (cm)$ <-- Answer

What is the value of the following expression 1.8 + 0.5(y + 6) - 2 t the power of 3 when y = 14?

Vikentia [17]

Answer:

The value of given expression is 3.8.

Step-by-step explanation:

Given:

$1.8+0.5(y+6)-2^3$

We need to find the simplified value of given expression using y =14

Solution:

Now we will substitute y =14 we get;

$1.8+0.5(y+6)-2^3\\\\1.8+0.5(14+6)-2^3$

Now using PEDMAS we will first solve the parenthesis we get;

$1.8+0.5\times20-2^3$

Now we will solve the exponent function we get;

we know that;

$2^3=8$

So we can say that;

$1.8+0.5\times20-8$

Now we will solve the multiplication operation.

$1.8+10-8$

Now we will perform addition operation.

$11.8-8$

And finally we will perform subtraction operation.

3.8

Hence The value of given expression is 3.8.
