Step-by-step explanation:
bc if you sub in 4 for x the equations on both sides are 0
check:
-4 + 4 = 0 -3 x 4 = -12

Did you do the math homework for math homework homework for math
So 4 triangular faces of the pyramid will have total area
<span>= 4 ×<span>12 </span>× base × height = 4 × <span>12 </span>× 34 × 58f<span>t2 </span>= 3944f<span>t2</span></span>
So <span>3944f<span>t2</span></span> of marble cover the faces of the pyramid.
<span> 5x + 6y= -12 7) x - 5y = 0 6) x +6y = - 42 8) 4x - 7y = -21 </span>
