Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.
Answer:
ok listen when looking at the graph the answer is easy its b
Step-by-step explanation:
For Value of x,
We know, 360 = 2( a+b)
180 = 4x+2x-6
180 = 6x-6
6x = 186
x = 186/6
x = 31
For value of y:
It would be equal,
5y = y+8
5y-y = 8
4y = 8
y = 2
SO, OPTION A IS YOUR ANSWER
Answer:
20 yd^2
Step-by-step explanation:
Your work is partially correct.
Assuming that the sides marked 8 yds and 2 yds are parallel, then the area of the trapezoid is
A = ( 8 yds + 2 yds)
------------------------ * 4 = 20 yd^2
2
