Answer:

h = 7.8

Step-by-step explanation:

A = 1/2*b*h

35.1 = 1/2*9*h . . . . dimensions apply to the base only

35.1*2/9 = h = 7.8 . . . m is the height of the triangular base.

Check:

The base is an equilateral triangle, so the height will be (9 m)*sin(60°) = 7.8 m.

_____

For the question asked, the surface area and slant height are irrelevant.

Factor completely x3 + 8x2 − 3x − 24.
Anna71 [15]

Answer:

<h2>x³ + 8x² - 3x - 24 = (x + 8)(x - √3)(x + √3)</h2>

Step-by-step explanation:

x^3+8x^2-3x-24\\\\=(x^2)(x)+(x^2)(8)+(-3)(x)+(-3)(8)\qquad\text{distribute}\\\\=x^2(x+8)-3(x+8)\\\\=(x+8)(x^2-3)\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=(x+8)(x^2-(\sqrt3)^2)\\\\=(x+8)(x-\sqrt3)(x+\sqrt3)
