Answer: X= -9
Step-by-step explanation:
Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.
Then subtract or add the like terms
5x-3x and 20+3. It will be 2x+23=5
Then add -23 to both sides
It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x
2x/2=-18/2 then the final answer is x= -9. I hope it help
20+x = 12+2x is the answer and x=8

Answer:
261.3cm3
Step-by-step explanation:
The prallelogram whose adjacent sides are equal and one vertex angle is 90 degrees is a square.
The value of angle 1 is 90 degrees as the diagonal of the square intersect at 90 degrees.

The value of y is 23.
The diagonal of the square bisect the vertex angle hence the angle of 3x is 45 degrees.

Thus, the value of x is 15 degrees.
The value of 12z is 45 degrees.

Thus, the required value of z is 3.75 degrees.
