Answer:
ABC= 60 XYZ=540
Step-by-step explanation:
The area of a triangle is 1/2*base*height so for ABC we need to find the height first. To do this we use pythag theorem, and create the equation 13^2=5^2+height^2 rearranging this we can figure out that sqrt(height)=13^2-5^2. For the base we do 2*5 since there are two congruent line segments both equal to 5. Using this we can do 1/2*12*10=area of ABC
For XYZ we can do 1/2*30*36=area of XYZ, we can do 2*15 since there are 2 congruent 15 length line segments at the base.
To find the value of y for the given value of x, just replace the x in the equation with 9, which is the given value of x.
y = 1 - 2x
Replace x with 9
y = 1 - 2(9)
2 times 9 is 18
y = 1 - 18
Simplify
y = - 17
That's your answer.
Have an awesome day! :)

Answer:
256
Step-by-step explanation:
V=1/3*π*4^2*7,46=124.993
32000/124.99=~256
Answer:
a = 5, b = -12
Step-by-step explanation:
By basic factoring, you get 9 - 12i + 
. Since 
is simply -1, the expression evaluates to 9 - 12i - 4, which is 5 - 12i.
