Answer:

216 meters

Step-by-step explanation:

make a 4 square box. put the numbers 10 & 2 on top an 8 & 10 on the side.then multiply...

8 * 10 = 80

8 * 2 = 16

10 * 10 = 100

&

10 * 2 = 20

then add all the numbers together.... 80+16+100+20 = 216 meters

the end. Can u mark me the brainliest when u get the chance? thnxs

Question 14 of 25What is the complete factorization of the polynomial below?x³+x² + 4x+4O A. (x-1)(x+2)(x+2)B. (x + 1)(x + 2)(x
mote1985 [20]

GIVEN:

We are given the following polynomial;

x^3+x^2+4x+4

Required;

We are required to factorize this polynomial completely.

Step-by-step explanation;

To factorize this polynomial, we start by grouping;

(x^3+x^2)+(4x+4)

We now take the common factor in each group;

\begin{gathered} x^2(x+1)+4(x+1) \\  \\ (x^2+4)(x+1) \end{gathered}

Next, we factorize the first parenthesis. To do this we set the equation equal to zero and solve for x as follows;

\begin{gathered} x^2+4=0 \\  \\ Subtract\text{ }4\text{ }from\text{ }both\text{ }sides: \\  \\ x^2=-4 \\  \\ Take\text{ }the\text{ }square\text{ }root\text{ }of\text{ }both\text{ }sides: \\  \\ x=\pm\sqrt{-4} \\  \\ x=(\pm\sqrt{-1}\times\sqrt{4}) \\  \\ x=\pm2i \end{gathered}

Therefore, the factors of the other parenthesis are;

(x+2i)(x-2i)

Therefore, the complete factorization of the polynomial is;

ANSWER:

(x+1)(x+2i)(x-2i)

Option C is the correct answer.

Question 7 (1 point)<br> Solve: 8x = 56
Hunter-Best [27]

Answer:

x = 7

Step-by-step explanation:

8x = 56

To solve this, we must simplify. To do this, we must divide each side by 8. This, in term, will give us the value of x.

8x = 56

----    ----

8       8

56/8 = 7

x = 7

Our answer is x = 7
