Answer:
12
Step-by-step explanation:
the opposite of -12 is 12
They are both drawn as right angled triangles so if we can constract them then they should obey pythagoras theorem
First traingle:- 8^2 = 64
7^2 + 6^2 = 49 + 36 = 85 so this does not obey the theorem and you cant draw it.
Second traingle: 9^2 = 81 and 5^2 + 7^2 = 25 + 49 = 75 so we cant draw that one either.
180 + 60x = 2,000
180 is how much money she has already, 60 is how much she makes per week, x is the amount of weeks, and 2,000 is her goal.
Answer:
width = 15
Step-by-step explanation:
a² + b² = c² This the the formula
(PLUG IN)
8² + b² = 17²
64 + b² = 289 (subtract 64 on both sides)
b² = 225 (square root)
b = 15
Hope this helps ya!!
Answer:
The average is 124
Step-by-step explanation:
When x=2 substitute into the equation given above
-3^2+79
9+79=88...(1)
When x=4
-3^4+79
81+79=160(2)
Average of (1) and (2)
160+88/2
=248/2
=124
Therefore the average rate is 124
