Answer:

x^2 − 5x − 36 = (x - 9)(x + 4)

Step-by-step explanation:

You need to find two numbers whose product is -36 and whose sum is -5.

-36 = -4 * 9; sum -4 + 9 = 4 wrong sum

-36 = -9 * 4; sum -9 + 4 = -5 right sum

The numbers are -9 and 4.

Answer: x^2 − 5x − 36 = (x - 9)(x + 4)

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.

Answer:

$x=58$

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total $360\textdegree - 294\textdegree= 66\textdegree$ .

Therefore, this means that our two smaller angles must equal 66°. So:

$(36)+(x-28)=66$

Solve for x. Add on the left:

$x+8=66$

Subtract 8 from both sides. Therefore, the value of x is:

$x=58$

The Perimeter Of A Parallelogram Is 72 Meters. The Width Of The Parallelogram Is 4 Meters Less Than It’s Length. Find The Length

saul85 [17]

The width would be x-4 and

Length would be x

Add all of the sides together

(x-4)+(x-4) + x + x =72,

Which would come out

4x-8=72

Subtract 8 fro, 72 and you get 64

Then divided 64 by 4

So. Width is 16 and length is 20 . given (x-4)
