Respuesta:
3x² + 5x - 2
Explicación paso a paso:
Dado que :
Área del rectángulo, A = largo * ancho
Dimensión = 3x - 1; x + 2
Área = (3x - 1) * (x + 2)
Área = 3x² + 6x - x - 2
Área = 3x² + 5x - 2
Answer:
$24.5 = 1 tank
Step-by-step explanation:
All you have to do is multiply.
Since 12.5 gallons = 1 tank,
and $1.96 = 1 gallon
to get the answer, the equation would be,
$1.96*12.5 = 1 tank
$24.5 = 1 tank

15. 2x+4y=5
Since you want to put it into y-intercept format (y=mx+b) first you want to minus 2x on both sides making it 4y= -2x+5, following you will divide by 4 on both sides making it y= -1/2x+ 5/4(1.25). The slope being -1/2x and the y-intercept hitting 1.25 on the y-axis.
17. 3x-3y=5. Like question 15 you will have to put it into y=mx+b format. So first you would minus 3x on both sides becoming -3y = -3x+5 then do the following: divide by -3 on both sides making the answer Y= x-5/3(-1.66666667) you can round it up to -1.67. Overall the answer should be y=x-1.67. 1.67 being the y-int meaning the line meets the y-axis at 1.67 and the slope being 1/1 to help you form the line.
