Answer:
d<3
Step-by-step explanation:
-7d+8>29
First lets remove the inequality for know
-7d+8=29
then remember to re add the inequality to the equation
-7d>21
since you divide by negative you switch
d<3
that is your answer
Coordinates are written in the form (x,y), x being a certain length along the horizontal x axis and y being a certain height along the vertical y axis. Positive y numbers are in the top half of the plane and negative y numbers are on the bottom. Positive x numbers are on the right side of the plane and negative x numbers are on the left. Therefore, (3,-7) would be 3 across to the right from the origin (where the x and y axes intersect) at (3,0) and 7 downwards from that point to (3,-7).
Answer:
a) As sides of squares are always equal.
So,
BC=CD
2b+CF=a+b
CF= a+b-2b
CF= a-b
b) Area of rectangle CDEF= CDxCF
=(a+b)(a-b)
=(a²-b²)
Hope it helps :-)
Step-by-step explanation:
(-3y^2+24y)(-6y^2-3y)
open the bracket and collect the like terms
-3y^2-6y^2+24y-3y
-9y^2+21y
