mart [117]

Answer:

B. 15 ft^3

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

V = (1/3)Bh

where B represents the area of the base, and h represents the height.

The base is apparently a rectangle, so its area is the product of its length and width:

B = L·W = (4.5 ft)(4 ft) = 18 ft^2

Then the volume is ...

V = (1/3)(18 ft^2)(2.5 ft) = 15 ft^3

15 cubic feet of sand will be needed to fill the base.

What is -3x^2-4x-4=0

ss7ja [257]

Answer:

<h2>no real solution</h2>

Step-by-step explanation:

$-3x^2-4x-4=0\qquad\text{change the signs}\\\\3x^2+4x+4=0\\\\\text{use the quadratic formula:}\\\\\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$\text{We have}\ a=3,\ b=4,\ c=4.\\\\\text{Substitute:}\\\\b^2-4ac=4^2-4(3)(4)=16-48=-32$
