Answer:
7*7
Step-by-step explanation:
49 = 7*7
As 7 is a prime number ( a number that can only be written as a product of 1 and itself), we are finished
AB=BC=CD together with the fact the horizontal lines are parallel implies that HG=GF=FE (can be proved using triangle similarity). So knowing FE=5.1 implies FG=5.1
Since we now know that the horizontal lines are equidistant, it means that ML=LK=KJ (same argument as above). Therefore KL=7.6.

Answer:
x = -12 x = -5
Step-by-step explanation:
-7x-60=x^2+10x
Add 7x to each side
-60=x^2+10x+7x
-60=x^2+17x
Add 60 to each side
0 = x^2+17x+60
Factor
What 2 numbers multiply to 60 and add to 17
12*5 = 60
12+5 = 17
0 = (x+12) (x+5)
Using the zero product property
x+12 = 0 x+5 =0
x = -12 x = -5
I feel sorry for but don't worry sometimes people fail but it's ok because I fail to not everyone get's good grades
Its very easy. Whats the math problem ill help you out.
