9-5= 4
4+2=6
And then +1 is 7
And all you have to do is put the s back in so the answer is:

Factor completely 2x^2 − 2x − 40. 2(x − 5)(x 4) (2x − 10)(x 4) (x − 5)(2x 8) 2(x − 4)(x 5)
Zina [86]
2x^2 - 2x - 40 = 2x^2 -10x + 8x - 40 = 2x(x - 5) + 8(x - 5)

= (x-5)(2x+8) = 2(x-5)(x+4)

<span>For this case, what you must do is find the area of the two rectangles shown in the figure.</span>

<span> We have then:</span>

<span> Rectangle 1:</span>

<span> A1 = (40) * (18)</span>

<span> A1 = 720</span>

<span> Rectangle 2:</span>

<span> A2 = (24-18) * (40-30)</span>

<span> A2 = (6) * (10)</span>

<span> A2 = 60</span>

<span> The area of the composite figure is:</span>

<span> A = A1 + A2</span>

<span> A = 720 + 60</span>

<span> A = 780 feet ^ 2</span>

<span> Answer:</span>

<span><span><span><span> the area of the figure is:</span></span></span></span>

<span><span><span> <span>C. 780 ft ^ 2</span></span>

Enter the ratio as a fraction in lowest terms 2 ft to 10 in.
Rufina [12.5K]
I think it's 2 5\6

because you have 2 whole fts and 10\12 of a foot which reduces to 5/6 when you divide the numerator and denominator by 2 which they have the highest common divider.
