when you subtract a negative number from any platitude number the equation changes to addition so you would add the value of the negative number to 1.
Area of paralellogram=legnth times height
l=legnth
h=height
area=96
lh=96
h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12
l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion
legnth=12cm
Answer:
-10w -20
Step-by-step explanation:
5(-2w-4)
Distribute the 5
5*-2w -5*4
-10w -20
Answer:
A
Explanation: horizontal line is 180 degrees, and the square means 90 degrees. So adding up the angles z + 90 + z =180
I don't get this question. Because if it is this simple, the two whole numbers are 40 and 42
