What is area of this shape

german

Answer:

132 ft squared

Step-by-step explanation:

One way is to divide the shape into a rectangle and a triangle, by drawing a vertical line.

This gives a rectangle that is 9 by 11, so has area 99.

The triangle has a base of 11 and height of 15 - 9 = 6.

So the area of the triangle = 1/2 x b x h = 1/2 x 11 x 6 = 33

So the total area is 99 + 33 = 132.

Find the value of x.

Brrunno [24]

Answer: x=133

Step-by-step explanation:

This is a hexagon that has a total of 720 degrees (which you can get by the formula of degrees = (# of sides – 2) * 180).

You first add up all your side:

150+130+97+120+90 +x = 587 + x

587+x = 720

x=133

Given a polynomial f(x), if (x − 4) is a factor, what else must be true?

ollegr [7]

Answer:

$f(4)=0$

Step-by-step explanation:

<em>The </em><em>Remainder Theorem</em><em> states that when you divide a polynomial $f(x)$ by a linear factor $(x-a)$ , where $a$ is a constant, the remainder is $f(x)$ evaluated at $x=a$ </em>

<em>Moreover, according to the </em><em>Factor Theorem</em><em>, an extension of the Remainder Theorem, if the remainder of the function $f(x)$ is </em><em>0</em><em> when evaluated at $x=a$ , then $(x-a)$ is said to be a factor of the polynomial $f(x)$ </em>

Given the 2 theorems above, it follows that if $(x-4)$ is a factor of $f(x)$ , then the remainder is equal to 0 when $f(x)$ is evaluated at $x=4$

Which means $f(4)=0$

Third answer choice is correct.

X=6<br> is a solution to the inequality x−5≤ 10<br><br> True or False?

vekshin1

Answer:

$\boxed{\sf{FALSE}}$

$\boxed{\sf{x\leq 15}}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

<h3>x-5≤10</h3>

<u>First, add by 5 from both sides.</u>

$\sf{x-5+5\leq10+5}$

<u>Solve.</u>

<u>Add the numbers from left to right.</u>

$\sf{10+5=15}$

$\Longrightarrow: \boxed{\sf{x\leq 15}}$

<u>Therefore, the solution is x≤15, which is our answer.</u>

I hope this helps you! Let me know if my answer is wrong or not.
