The answer to the expansion of the expression, 3+5^2 is 28
<h3>How to expand an expansion</h3>
An expansion of an expression is the evaluation of the expression to its simplest form
Given:
3+5^2
= 3 + 5²
= 3 + (5 × 5)
= 3 + 25
= 28
Therefore, answer to the expansion of the expression, 3+5^2 is 28

Answer:
Step-by-step explanation:
Area of a Segment in Radians A = (½) × r2 (θ – Sin θ)
Area of a Segment in Degrees A = (½) × r 2 × [(π/180) θ – sin θ]
Its true because you have to subtract in the long version so do you want me to show it to you?
Answer:
Step-by-step explanation:
9x⁴ – 2x² – 7 = 0
Let's say that u = x²:
9u² – 2u – 7 = 0
Factor:
(u – 1) (9u + 7) = 0
u = 1, -7/9
Since u = x²:
x² = 1, -7/9
x = ±1, ±i √(7/9)
