Answer:
Step-by-step explanation:
P = x^2 + 6
Solving for 4x^2:
P = x^2 +6
P - 6 = x^2
4(P - 6) = 4x^2
Substitution:
2x^2-y
Plug in the values.
2(3)^2-(-2)
2(3)^2+2
Exponents first.
2*9+2
18+2
20
The answer is 20.
I hope this helps!

Simplify the expression
6² + 9²
6² = 6 x 6 = 36
9² = 9 x 9 = 81
36 + 81 = 117
117 is a rational number ∴ <span>6</span>²<span> plus 9</span>² is rational
hope this helps
Answer:
LCM (8,10) = 2 × 2 × 2 × 5 = 40
Step-by-step explanation:
Least common multiple is the smallest number that is multiple of both the given numbers.
Example: LCM of 2 and 3 is 6 .
6 is a multiple of both 2 and 3 .
Given numbers are 8 and 10
First write both in factor form,
⇒ 8 = 2 × 2 × 2
⇒ 10 = 2 × 5
We find LCM by writing common terms one times and multiplying all terms together,
Here, 2 is common to both 8 and 10 so we write it once only.
Thus, LCM (8,10) = 2 × 2 × 2 × 5 = 40.
