HELPP DESPERATELY

Answer:

Point Q = (3.6, 1.4)

Step-by-step explanation:

The 4:1 ratio should first be changed to 4/5.

y2-y1= 2+1 = 3 which as a fraction is 3/1, now multiply that which the earlier fraction 4/5 to get 12/5 = 2.4

x2-x1= 4-2= 2 which as a fraction is 2/1, do the same as earlier, multiply by 4/5 to get 8/5 = 1.6

now add these to A to get point Q

2+1.6= 3.6

-1+2.4=1.4

Point Q = (3.6, 1.4)

Select the correct product.<br><br> (x 2 + 4x + 8)(2x - 1)

marusya05 [52]

Answer:

$\large\boxed{(x^2+4x+8)(2x-1)=2x^3+7x^2+12x-8}$

Step-by-step explanation:

Use FOIL: <em>(a + b)(c + d) = ac + ad + bc + bd</em>

$(x^2+4x+8)(2x-1)\\\\=(x^2)(2x)+(x^2)(-1)+(4x)(2x)+(4x)(-1)+(8)(2x)+(8)(-1)\\\\=2x^3-x^2+8x^2-4x+16x-8\qquad\text{combine like terms}\\\\=2x^3+(-x^2+8x^2)+(-4x+16x)-8\\\\=2x^3+7x^2+12x-8$
