<span>4x^2 - 25
= (2x)^2 - 5^2 .................using a^2 - b^2 = (a+b)(a-b)
= (2x + 5)(2x - 5)</span>
= m^4 + 28m^2 - 36m^4 + 8m^5
= 8m^5 - 35m^4 + 28m^2
Answer
polynomial in standard form
8m^5 - 35m^4 + 28m^2
Answer:
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is 13
With m∠65° as the reference angle,
y represents the adjacent side of the right angle triangle.
x represents the opposite side of the right angle triangle.
To determine the value of x, we would apply the sine trigonometric ratio which is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 65 = x/13
x = 13Sin65 = 13 × 0.906
x = 11.8 to the nearest tenth
