9^-8 • 9^-2 = a^b
9^-10 = a^b
a = 9
b = -10
You get this results from comparing terms
Answer:
x=7
step-by-step explanation:

5(2x+10) =3×40
10x + 50 = 120
10x =120-50= 70
x = 70/10= 7
Answer:
value of X=180-(ABC + ACB)
=180-(42+90)
=180-132
=48
Answer:
Yes.
Step-by-step explanation:
Searched it up and I am just hoping it's right. Have a good one ;)
Answer:
x=4 and y=2
Step-by-step explanation:
I'm not 100% sure but I substituted different numbers into the equation:
If x=4 and y=2 then 4+2=6 and 3x2=6 so it would be 6=6
Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9
I'm more confident with x=4 and y=2 because of the small size of the triangle.
I hope this helps! Good luck! :)
