Answer:

9(x-4) [5x-19]

Step-by-step explanation:

45(x-4)^2+9(x-4)

We can factor out a 9 (x-4)

9 (x-4) [5(x-4) +1)]

Distribute in side the parentheses

9(x-4) [5x-20+1]

9(x-4) [5x-19]

Answer:

9(5x−19)(x−4)

Step-by-step explanation:

First you have to distribute

45x^2+−360x+720+(9)(x)+(9)(−4)

45x^2+−360x+720+9x+−36

Then you have to combine like terms

45x^2+−360x+720+9x+−36

(45x^2)+9-360+9x)+(720+-36)

45x^2−351x+684

9(5x−19)(x−4)

Hope this helped!

Multiply 7x13 in binary.
scoray [572]

Answer:

1011011

Step-by-step explanation:

The binary multiplication is pretty much like the decimal one, we have just to remember that in the binary system 1+1 = 10.

First, convert 7 and 13 to binary

7 = 111

13 = 1101

now multiply with the same rules as in decimal

        1101x

          111

   --------------

         1101+

       1101  +

     1101

    1111

 -------------

   1011011

The last row of digits are the carry bits.

So 7*13 = 1101*111(binary) = 1011011 (binary)

Plz help i will mark brainliest
Rama09 [41]

Answer:

22 units

Step-by-step explanation:

The perimeter of a rectangle is 2(width + length)

In this case width = 2z + 2 and length = 3z + 3

replacing everything known:

110 = 2(2z + 2 + 3z + 3)

110/2 = (5z + 5)

55 = 5z + 5

55 - 5 = 5z

50 = 5z

10 = z

Segment PQ is the same as SR = 2z + 2

Replacing z = 10

PQ = 2(10) + 2
