The first thing you would do is substitute the 10 in for 'w' and 535 in for 'c'. 535 = 235 + 30(10) 535 = 185 + 35(10) Then, you would just solve the equations. 535 = 235 + 30(10) 30(10) = 300 300 + 235 = 535 So the first equation is true, and we know for a fact that Larry's Landscaping charges $535 for a spring cleaning and weekly yard maintenance for 10 weeks. On to the next equation. 535 = 185 + 35(10) 35(10) = 350 185 + 350 = 535 So, the second equation is true also. And we also know for a fact that Joe's Landscaping charges $535 for a spring cleaning and weekly yard maintenance for 10 weeks. So, now that we know that they will end up charging the same amount of money for a spring cleaning and weekly yard maintenance, the only answer that fits that is C. The cost for lawn maintenance is the same, $535, for both landscaping companies after 10 weeks. Hope this helps!
He can either measure the third side length, apply the Pythagorean theorem to find the height of the triangle, and then calculate the area, or he can find the measure of the included angle between the known side lengths and use trigonometry to express the height of the triangle and then determine the
If you know the formular a^3+b^3=(a+b)(a^2-ab+b^2), you can solve this problem. 8 is 2 cubed, so x^3+2^3=(x+2)(x^2-2x+4) so the other quadratic factor is x^2-2x+4
