Answer:
3rd one is no. the others are all yes
Answer:
A and E
Step-by-step explanation:
substitute and odd number into every equation :)
Well, AEB is 28, and CED is 65,and you want to add them, so that would be 65+28, which equals 80+13=93, so the answer is b.
The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
