The vertical angle diagonally across the equation, (3x +9) is also (3x+9).
Since m is perpendicular to n, that means that (3x + 9) + (x + 21) = 90° This is so because perpendicular lines form right angles which have the measure of 90°
3x + 9 + x + 21 = 90
4x + 30 = 90
4x = 60
x = 15
Answer:
The answer is b.
Step-by-step explanation:
If you divide y by x for every pair, you will get the number 4. This means that it is proportional because each pair has the same solution.
Hope this helps!

The answer is D. The intersection of the sets is the set of all outcomes in the sample space of events a and B
Answer:
1464 inch²
Step-by-step explanation:
given first prism sides: length - 10 width - 10 height - 10
given second prism sides: length - 12 width - 12 height - 12
using the formula below:
for the first prism:
2(10*10+10*10+10*10)
600 inch²
for the second prism:
2(12*12+12*12+12*12)
864 inch²
So total surface area is (864 inch² + 600 inch²) =1464 inch²
