I would answer the problem but first upload the diagram
Answer:
Step-by-step explanation:
Area of rectangle = length * width
= (3x + 2)(4x + 10)
= 3x *(4x + 10) + 2*(4x + 10)
= 3x *4x + 3x *10 + 2*4x + 2*10
= 12x² + <u>30x + 8x</u> + 20 {Combine like terms}
= 12x² + 38x + 20
Regular price is $120
And they are on sale for 35% off.
120 * 35/100 = $42
So they are $42 off.
Then;
Sale price is $120 - $42 = $78
