Answer:
What is the equation?
Step-by-step explanation:
Answer: z + 17
Step-by-step explanation:
1) DISTRIBUTE:
11 + 2z + 6 - z
2) COMBINE LIKE TERMS
z + 17
This is a question that can be solved with Pythagorean Theorem since it is a right triangle. The longest side, 29, is the hypotenuse and the sides 21 and x are the legs. So, the Pythagorean Theorem states,

Where,
c is the Hypotenuse, a and b are the legs. Putting the respective values gives us,

So, 20 is the side length of x.
ANSWER: 20
Answer:
240
Step-by-step explanation:
Gain=25%
Gain=selling price - cost price
Gain = ((selling price - cost price )× 100)/ cost price
25c=(4800-c)100
25c=480000-100c
125c=480000
cost price = 3840
second statement
The selling price was 4080
Cost price 3840
therefore
Gain=selling price - cost price
Gain = 4080-3840
=240
Somewhere in the text, it must say that x = 2 and y = -1 or else, the values just seem made up out of thin air.
