Please help me with this question, image attached

Goryan [66]

Answer:

$W=(x-6)\ m$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

we have

$A=(x^{2} -11x+30)\ m^2$

$L=(x-5)\ m$

substitute the given values in the formula of area

$(x^{2} -11x+30)=(x-5)W$

Remember that

$x^{2} -11x+30=(x-5)(x-6)$ ----> by completing the square

substitute

$(x-5)(x-6)=(x-5)W$

Simplify

$W=(x-6)\ m$

Solve for X. -8x - 4(x - 4) = 88 Please show work

Hi there!

»»————-　★　————-««

I believe your answer is:

$\huge x=-6$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving for 'x'...}}\\\\-8x-4(x-4)=88\\-------------\\\rightarrow -8x-4x+16=88\\\\\rightarrow -12x + 16 = 88\\\\\rightarrow -12x + 16 - 16 = 88 - 16\\\\\rightarrow -12x = 72\\\\\rightarrow \frac{-12x=72}{12}\\\\\rightarrow \boxed{x=-6}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Triangle U S T is shown. Angle U S T is 100 degrees. The length of U S is 9, the length of S T is 10, and the length of U T is s

Vladimir [108]

By solving through law of cosines the length s can be written as $s^{2} =9^{2} +10^{2} -2*9*10cos(100)$ .

Given the length of US is 9, the length of ST is 10 and the length of UT is s and the angle UST is 100 degrees.

According to law of cosines a length can be written as $c^{2} =a^{2} +b^{2} -2abcos g$

where c is the side opposite to the given angle and a and b are other sides , g is the angle given.

$s^{2} =9^{2} +10^{2} -2*9*10cos(100)$

where s is the length of the side opposite to the angle given, the length of other sides are 9 and 10 where the angle is 100.

Hence the fourth option is correct which is s^{2} =9^{2} +10^{2} -2*9*10cos(100).
