Answer:
<u>For</u><u> </u><u>A</u>
• The equation above has a common bracket "(x + 1)". So, let's first factorise out that bracket:
• now in the second bracket, the common factor is x and 2.
• Final answer;
<u>For</u><u> </u><u>B</u>
• In the equation, the common bracket is (x + 2).
So let's first factorise it out:
• In the second major bracket, the common bracket is (x - 1). so factorise it out:
• Final answer:
First subtract the C to move it to the other side
c-P=b+4a
Then subtract the 4a as well
4a-c-p=b
Let A be the angle of 79 degrees
B be the angle of (5y-4) degrees
C be the angle of (x+5) degrees
D be the angle of (9z-7) degrees
According to the property of parallelogram
Opposite angles are equal
We get, angle A = angle C
Since angle A = 79 degrees
And angle C = (x+5) degrees
We get, x+5=79
=> x=79-5=74.
Angle B = Angle D
(5y-4)=(9z-7)
Since there’s two variables here, we can’t use the property of “opposite angles are equivalent”
We have to use another property which is adjacent angles are equal
Therefore, we can find angle D
Angle D + Angle A=180
=> 9z-7 =180-79
z=108/9
z=12
Since (5y-4)=(9z-7)
Substitute z=12 in
We get, 5y-4=101
y= 105/5
y= 21
Therefore, x=74, y=21 and z=12.
