Evaluate the following expressions if a = 2, b = 3, x = 4, and y = 5.<br> b^2+3(2x-y)

butalik [34]

Hi there! Hopefully this helps!

-------------------------------------------------------------------------------------------------------

<h2 /><h2>Answer: 18</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />

First we need to substitute the value of the variable into the expression.

$b^{2}+3(2x-y)$ = $3^{2} + 3 (2(4)-5)$ .

Now we need to solve $3^{2} + 3 (2(4)-5)$ .

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$3^{2} + 3 (2(4)-5)$

First, calculate 3 to the power of 2 and get 9.

$9+3(2\times 4-5)=18$

Multiply 2 and 4 to get 8.

$9+3(8-5) =18$

Subtract 5 from 8 to get 3.

$9+3\times 3 =18$

Multiply 3 and 3 to get 9.

$9+9 =18$ .

<h2>And the answer is, you guessed it, 18!</h2>

Which is the logarithmic form of 4^5 = 1024

leva [86]

Answer:

$Log_41024=5$

Step-by-step explanation:

The change of form formula (exponential to logarithm) is:

$a^x=b\\Log_ab=x$

Looking at the problem given, we can simply write the logarithmic form as:

$4^5=1024\\Log_41024=5$

This is the answer.

Solve for x with an explanation pls

Tatiana [17]

Answer: 9

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle.

$a^2+b^2=c^2$

$(\sqrt{63}) ^2+x^2=12^2\\63+x^2=144\\x^2=81\\x=9$
