Answer:
44
Step-by-step explanation:
Given, 3x^2 + 3y^2 = 42
=>3(x^2 + y^2) = 42 =>x^2 + y^2 = 42/3= 14
Thus,
= (x - y)^2
= x^2 + y^2 - 2xy
= (x^2 + y^2) - 2xy
= 14 - 2(-15)
= 14 + 30
= 44

Answer:
Step-by-step explanation:
The angle opposite the 10 meter length is greater than 90. It calculates out to be about 130 degrees. The triangle is obtuse.
As a note that dog is going to be very uncomfortable. He does not have much room to move around. Let's hope he's something like a Chihuahua. The height of the triangle from the 130 degree angle's apex is about 2 meters.
Answer:
7 ⁻²²
Step-by-step explanation:
7¹⁶/7¹² = 7⁻¹⁸/7ˣ
7⁽¹⁶⁻¹²⁾ = 7⁽⁻¹⁸⁻ˣ⁾
16 - 12 = - 18 - x
4 = - 18 - x
x = - 18 - 4
x = - 22
