Answer: B and C
Explanation:
x^2 + 3x - 18 = 0
(x + 6)(x - 3) = 0
Set x + 6 = 0 => x = -6
Set x - 3 = 0 => x = 3
Answer:
If you mean 1.5 * 1.5^2 then the answers 3.375
Step-by-step explanation:
Hello :
<span>√3 = 3^(1/2)
243 = 3^(5)
subsct in :
</span><span>243√3 =3^a
</span> 3^(5)×3^(1/2) = 3^a
3^(5+1/2) = 3^a
a = 5+1/2 = 11/2
a = 5.5
1.2625 i dunno if this is correct though on my calculations
Answer:
x = 18
Step-by-step explanation:
Since that is a right angle, we know that the total degrees of the angle is 90 degrees.
1) Based off of that, you can form the equation: 3x + 2x = 90.
2) solve the equation for x. Combine like terms: 3x + 2x = 5x.
5x = 90
3) So now, divide both sides by 5. 90 / 5 = 18
x = 18
Therefore, the correct answer is x = 18.
