Hello,

Let's x and y the 2 numbers

x*y=24
x+y=-11==>x=-11-y
==> (-11-y)y=24
==>-11y-y²-24=0
==>y²+11y+24=0
Δ==11²-4*24=25=5²
y=(-11+5)/2 or y=(-11-5)/2
==>(y=-3 and x=-11+3) or (y=-8 and x=-11+8)

Sol={(-8,-3),(-3,-8)}

The 2 numbers are -3 et -8.

<h2>○=> <u>Correct answer</u> :</h2><h2>\color{plum} = \tt\bold{30 \: cubic \: inches}</h2><h3>○=> <u>Steps to derive correct answer</u> :</h3>

Given :

Base area of Ms. Jones decorative pyramid = 6 inches²

Height of the decorative pyramid = 15 inches

We know that :

\color{hotpink}\tt \: volume \: of \: a \: triangular \: pyramid\color{plum} \tt \: =  \frac{1}{3}Bh

Volume of the decorative pyramid :

=\tt  \frac{1}{3}  \times 15 \times 6

=\tt \frac{15 \times 6}{3}

=\tt  \frac{90}{3}

\color{plum} =\tt 30 \:  {inches}^{3}

Therefore, the volume of the decorative pyramid with Ms. Jones = 30 inches³
