the theory is ab=cd where the lines across form eachother are a and b and the other two lines are a and d
a=7
b=n+4
c=5
d=n+8
7(n+4)=5(n+8)
7n+28=5n+40
2n+28=40
2n=12
n=6
Answer:
-4
Step-by-step explanation:
Numbers decrease on a number line as you go left. So, to find a number to the left of -1, you need to find a number that is smaller. Since negative numbers decrease in value as they get further from 0, -4 must be smaller than -1. All other values listed will be to the right of -1.
Answer:
19/18
Step-by-step explanation:
substitute the value of m(11/6) in m-7/9
which is equal to 11/6 -7/9 =19/18
Step-by-step explanation:
Area of rectangle= l x b
= 245 x 245
=60025
Area of triangle = (1/2) x b x h
=(1/2) x 245 x 245
=30012.5
Area of shaded part = Area of rectangle - Area of triangle
=60025 - 30012.5
=30012.5
