Answer:

It is B. (36√5 + 36) ft^2.

Step-by-step explanation:

Total area = area of the base + 4 * area of the triangular side.

The slant height of a triangular side = √(6^2 + 3^2)

= √45

= 3√5

The area of this side = 3 * 3 √5

= 9√5.

Therefore the total area of the pyramid

= 6^2 + 4*9√5

= (36 + 36√5) ft^2.

$\to \sf(3x^3-4-3x) + 8 - 2x^3$

$\to \sf3x^3-4-3x + 8 - 2x^3$

Solve x2 + 8x − 3 = 0 using the completing-the-square method.

$(a+b)^2=a^2+2ab+b^2\\------------------\\\\x^2+8x-3=0\ \ \ |add\ 3\ to\ both\ sides\\\\x^2+2x\cdot4=3\ \ \ |add\ 4^2\ to\ both\ sides\\\\x^2+2x\cdot4+4^2=3+4^2\\\\(x+4)^2=3+16\\\\(x+4)^2=19\iff x+4=-\sqrt{19}\ or\ x+4=\sqrt{19}\\|subtract\ 4\ from\ both\ sides\\\\\boxed{x=-4-\sqrt{19}\ or\ x=-4+\sqrt{19}}$

the third side of an isosceles triangle is 8 inches shorter than the other two sides the perimeter of the triangle is 70 inches

dezoksy [38]

Isosceles triangle has 2 sides that are the same length. So what you have is three sides that measure: x, x, and (x-8). 70 = x + x + (x-8).
70 = x + x + x - 8
78 = 3x
x = 26.
and 26 - 8 = 18.
So two of your sides are 26 inches and the last side is 18 inches.
