Question 1 is factored form
Question 2 is standard form
Question 3 I think is +3
Question 4 is A
Question 5 it has no real solution
Answer:
This covers laws of Exponents or indices
Step-by-step explanation:
9^2 = 81
9^-2 = 1/9^2 = 1/81 (inverse)
9^-81 = 1/9^81
9^-9 = 1/9^9
1/81
1/9
The question is vague. Please update
Answer:
56°
Step-by-step explanation:
hii!
to solve this, we need to know that the angles of a triangle all add up to 180 degrees.
we are going to make an x equation here.
2x+3x+40=180
5x+40=180
-40 -40
5x=140
/5 /5
x=28
angle a is 2x, so the answer would be 28*2 which is 56°
hope this helped out :)
