Anettt [7]

Answer:

The correct option is B). $2x^{2}+16x+10$

Step-by-step explanation:

Given function is $(2x+4)^{2}-(2x^{2} +6)$

On simplifying,

= $(2x+4)^{2}-(2x^{2} +6)$

= $[4x^{2}+16x+16]-(2x^{2} +6)$

= $4x^{2}+16x+16-2x^{2}-6$

= $2x^{2}+16x+10$

Thus, The correct option is B). $2x^{2}+16x+10$

inessss [21]

Answer:

It will take turtle $2\frac{2}{5} \ hour$ to reach the pond.

Step-by-step explanation:

Given:

A turtle can walk 1/12 of a kilometer in an hour.

The turtle is 1/5 of a kilometer away from a pond.

Now, to find the time it will take the turtle to reach the pond.

<u>Speed</u> of turtle = $\frac{1}{12}\ kilometer\ per\ hour.$

<u>Distance</u> of turtle from the pond = $\frac{1}{5} \ kilometer.$

Now, to get the time it will take turtle to reach the pond we put formula:

$Time=\frac{Distance}{speed}$

$Time=\frac{\frac{1}{5}}{\frac{1}{12}}$

$Time=\frac{1}{5} \times \frac{12}{1}$

$Time=\frac{12}{5}$

$Time=2\frac{2}{5}\ hour.$

Therefore, it will take turtle $2\frac{2}{5} \ hour$ to reach the pond.

√32 = √2×2×2×2×2

Match 2 identical numbers one at a time and bring them out. ;

√32 = 2×2√2

√32 = 4√2 correct answer!

find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:

4√2 × 4√2 = 16×√4 = 16×2 = 32 correct!

hope it helps you <3
