The correct answer is option D

The solution is shown below:

$x^{2} +16 \\ \\ 
= x^{2} +(4)^{2} \\ \\ 
= x^{2} -(-1)(4)^{2} \\ \\ 
= x^{2} -i^{2} (4)^{2} \\ \\ 
= x^{2} -(4i)^{2} \\ \\ 
=(x+4i)(x-4i)
$

Which expression is equivalent to –5(6x – 3) – 4(–2x + 1) + 3(4x) – 8?

Sedaia [141]

Answer:

C = -10x+3

Step-by-step explanation:

So the simplified version of the main expression is -10x+3. after finding the main expression you just need to simplify the rest of them too.

A. = -10x+9

B. = 8x-9

C. = -10x+3

D. = -10x-3

Now that you simplified all the expressions, you can pick out the one that's the same as the target expression, which is C.

A major baseball diamond is a square with side lengths of 90 feet.

iren2701 [21]

Answer: $\bold{a)\quad 90\sqrt2\qquad \qquad b)\quad 45\sqrt2}$

<u>Step-by-step explanation:</u>

Since you are looking for the distance from home plate to second base, you are actually looking for the length of the diagonal of the square. Use the Pythagorean Theorem: a² + b² = c² where a and b are the side lengths and c is the length of the diagonal.

$90^2+90^2=c^2\\8100+8100=c^2\\16200=c^2\\\sqrt{16200}=c\\\boxed{90\sqrt2}=c\qquad \qquad \text{which is approximately 127.28}\\\\\\\\\text{Halfway between home plate and 2nd base means divide that length by 2:}\\\\\dfrac{90\sqrt2}{2}=\boxed{45\sqrt2}$
