<span>y = x^2 +2x - 35</span>
x-intercept y=0
0 = <span>x^2 +2x - 35
</span>0 = <span>x^2 -5x + 7x - 35 //factoring with leading coefficient
</span>0 = x(x-5) + 7(x-5)
0 = (x+7)(x-5)
x=-7 or x=5
answer: C. -7 and 5
Answer: 2 5/6 I think.
Wait no. I just did the math and it would be 2 1/2

multuply the base times the hight in which case the base is 21 and the hight is 12 then devide that answer by 2. so it should look like this 21 * 12 all over 2
A trick is to replace the "of" with a multiplication symbol"
the 30 dollar is (5/6 of the total cost =>30=(5/6)*c =>c=30*(6/5)=36
the game cost 36 dollars
