The answer is 35
Since they are supplementary they both equal 180 degrees.
(3x+10)+(2x-5)=180
Add them up
5x-5=180
Subtract 5 from both sides
5x=180-5
5x=175
Divide 5 from both sides
x=35.

Answer:
30, 5 , 21
Step-by-step explanation:
substitute the values of x into f(x) , then
f(- 5) = (- 5)² + 5 = 25 + 5 = 30
f(0) = 0² + 5 = 0 + 5 = 5
f(4) = 4² + 5 = 16 + 5 = 21
Remember property of exponents
add exponents of same base
ok so
50,000 is 5 times 10^4
so
50000 times 10^15=
5 times 10^4 times 10^15=
5 times
=
5 times 10^19
