Answer:
9
Step-by-step explanation:
Take the coefficient of the x term
6
Divide it by 2
6/2 =3
Square it
3^2 =9
This is what we add for a perfect square
First one.
Since the two angles are congruent through vertical angles theorem,
5x = 6x - 8
5x - 6x = -8
-x = -8
x = 8
Second one.
Use the 180° rule.
(8x - 2) + (2x + 2) = 180
8x - 2 + 2x + 2 = 180
8x + 2x + 2 - 2 = 180
10x = 180
x = 180 / 10
x = 18
Third one.
Vertical angle theorem.
7x = 5x + 40
7x - 5x = 40
2x = 40
x = 40 / 2
x = 20
Answer:
C x = 4096
Step-by-step explanation:
log8 x = 4
Raise each side to the base of 8
8^ log 8 (x) = 8^4
x = 8^4
x = 4096
Answer:
1/20
Step-by-step explanation:
The only way it can equal 2 is if both spinners land on 1 because 1 + 1 = 2.
The probability of the 1st spinner landing on 1 is 1/4.
The Probability of the 2nd spinner landing on 1 is 1/5.
To find out the Probability of them landing together it would be 1/5 times 1/4 which equals 1/20.
