Answer:
A perfect score on a test
Step-by-step explanation:
Since the score gets subtracted for each wrong answer, if x=0 then then nothing would get taken away from the initial 80
4x-2x-7x= -5x
-5-3=-8
-5x-8
Answer:
Step-by-step explanation:
Given linear inequalities of the point (2,3)
So.
(X-2)(X-3)=0
x^2-2x-3x+6=0
x^2-5x+6=0
It's solutions is x^2-5x+6.
Answer:
Length=22.5cm, Breadth=11.5cm
Step-by-step explanation:
Let length be l and width be w.
w+22=l
w+w+w+22+w+22=90
4w=90-22-22
=46
w=46 divided by 4
=11.5
l=11.5+11
=22.5
Hence,
Length of rectangle=22.5cm
Breadth of rectangle=11.5cm
