torisob [31]

Let x = total sales of baked goods remember 20% = .20 as a decimal

divide both sides by .20

.20x/.20 = $600/.20

x = $3000 the total sales of baked goods

CHECK: 20% times $3000 = .20 times $3000 = $600

What is the solution: (9x+2)(4x^2+35x-9)=0

Dmitrij [34]

$(9x+2)(4x^2+35x-9)=0\\\\9x+2=0\\9x=-2\\x=-\frac29\\or\\4x^2+35x-9=0\\\Delta=1225+144=1369\ \ \sqrt{\Delta}=37\\x_1=\frac{-35-37}{2 \cdot 4}=-9\\\\x_2=\frac{-35+37}{2\cdot 4}=\frac14\\\\x\in\{-9,-\frac29,\frac14\}$
