12 would be 8 times and then those options would be times by 9 which gives you 864
Answer:
All you need to do is move all terms to the left side and set equal to zero
The Answer is x = 16 Hope this helps :)
Step-by-step explanation:
The value of n would be 2.2. You would find this by distributing -6.5 into the parentheses which gives you -6.5n+32.5=18.2. Subtract 32.5 from both sides and you have -6.5n=-14.3. Divide -6.5 on both sides and you get n=2.2

Answer:
7.3
Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-5-(-3))² +(1 -8)²) = √((-2)² +(-7)²) = √(4+49) = √53
d ≈ 7.28011 ≈ 7.3 . . . units
XZ ≈ 7.3
Answer:
8
Step-by-step explanation:
sin theta = opposite side/ hypotenuse
sin 30 = 4/x
Multiply each side by x
x sin 30 = 4
Divide each side by sin 30
x sin 30 /sin 30 = 4 sin 30
x = 4 /sin 30
We know that sin 30 = 1/2
x = 4 / 1/2
x = 8
