Answer:
Step-by-step explanation:
∣∣2. 8−(−9. 4)∣∣
∣∣2. 8+(−9. 4)∣∣
So (positive integer)-x-y can be negative
so to get a negative number as your result/answer, x+y must be greater than (positve integer) so for example
lets say (positive integer)=8
x+y must be greater than 8 to make the equation negative so
example
x=5
y=4
x+y=9
8-9=-1
Answer:
63
Step-by-step explanation:
9x7=(10x7)-1x(7)
=70-7
=63
A)106°- angle at the centre is half of the angle at the circumference
b)74°- when a tangent meets a radius a right angle is created(90+90+106)= 286 360-286= 74°
