The rectangle below has an area of x² – 6x – 7 square meters and a width of 3 – 7 meters.
natta225 [31]

Answer:

The expression which represent the length of the rectangle is x + 1

Step-by-step explanation:

Given as :

The Area of rectangle = x² - 6 x - 7  square meters

The width of the rectangle = w = x - 7 meters

Let The length of rectangle = L meters

Now, <u>According to question</u>

∵ Area of Rectangle = Length × width

or, x² - 6 x - 7  meters² = L meters × w meters

or, x² - 6 x - 7 = L × (x - 7)

or, x² - 7 x + x - 7 = L × (x - 7)

or, x (x - 7) + 1 (x - 7) = L × (x - 7)

or, (x - 7) (x + 1) = L × (x - 7)

∴ L = \frac{(x - 7)\times (x + 1)}{(x - 7)}

I,e L = x + 1

So, The length of rectangle = L = x + 1

Hence,The expression which represent the length of the rectangle is x + 1 Answer

Simplify the square root of -72
kupik [55]

Answer:

6i\sqrt{2}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} = \sqrt{ab} and \sqrt{-1} = i

Given

\sqrt{-72}

= \sqrt{36(2)(-1)}

= \sqrt{36} × \sqrt{2} × \sqrt{-1}

= 6\sqrt{2} × i

= 6i\sqrt{2}

(8x4+64x3+3x-28)÷(x-8)
mamaluj [8]

check the picture below.


recall that the division is done with the dividend and divisor sorted in descending order, notice the dividend has a jump from x³ to x, so the x² is missing, but is really there, but it has a coefficient of 0, as you see there in red, so we add any missing terms on either side.
