False
because
(a+b)(c+d)=ab+bc+ad+bc
we look at bd
(x+3)(x+1)
bd=3*1=3
the last number is 4
not 3
if we were to expand it we would get
x²+4x+3
false
Yonna, this is the solution to the problem:
Side 1 of the tablet = (4x + 3) cm
Side 2 of the tablet = (-4x² - 2x - 3) cm
Area of the tablet = Side 1 * Side 2
Area of the tablet = (4x + 3) * (-4x² - 2x - 3) cm²
Area of the tablet = (4x * -4x²) + (4x * -2x) + (4x * -3) + (3 * -4x²) + (3 * -2x) + (3 * -3)
Area of the tablet = -16x³ - 8x² - 12x - 12x² - 6x - 9 cm²
Area of the tablet = -16x³ - 20x² - 18x - 9 cm²
