The number is 10.
x/5 = x-8
You multiply both sides by 5.
x = 5(x-8)
x = 5x-40
Subtract 5x from both sides
-4x = -40
x= -40 / -4
x=10
Answer:
-6,2
Step-by-step explanation:
im not sure what the answer is
By Pythagoras Theorem,
Height of Triangle = (1.7^2-1^2)^0.5 = (1.89)^0.5= 1.37 in
Area of one triangle = 1.374772708* 2*0.5= 1.374772708in^2
area of polygon = 5*1.374772708in^2=6.87in^2 = 6.9in^2
answer is b
-5/8 or -8/5 so that is tgd answer yeah
