Answer:

Here are the formulas

Cube/Rectangular Prism:

Volume = Length*width*height

Surface area = 2(wl+hl+hw)

Lateral area= Area of vertical faces

Base area = length*width

Regular hexagonal prism:

Volume : (3sqrt3/2)*a^2*h

Surface Area = 6ah+3sqrt(3)a^2

lateral area: 6ah

base area = 3sqrt(3)s^2/2

Triangular prism

Volume: The volume of a triangular prism can be found by multiplying the base times the height.

Surface area: A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

Etc.

Answer:

Step-by-step explanation:

$(3+\sqrt{-16})(6-\sqrt{-64})=(3+4\sqrt{-1})(6-8\sqrt{-1})=2(3+4\sqrt{-1})(3-4\sqrt{-1})\\\\=2(3^2-(4\sqrt{-1})^2)=2(9-(-16))\\\\=2(25)=50$

We make use of the special form for the difference of squares:

(a+b)(a-b) = a²-b²

Factor 1 and 2. You do NOT need to show or explain steps for 1-2.

Answer:

Step-by-step explanation:

x² + 9x + 18 = x² + 6x + 3x + 18

= x(x + 6) + 3(x + 6)

= (x + 3)(x + 6)

x² + 16x + 63 = x² + 9x + 7x + 63

= x(x + 9) + 7( x+ 9)

= (x + 7)(x + 9)

y² + 13y + 36 = y²+ 9y + 4y + 36

= y(y + 9) + 4(y + 9)

= (y + 4)(y + 9)

(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).

Therefore, Lyndsey's answer is wrong.

(b). Factors are (y + 4) and (y + 9).

(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).
