Answer:
(x + 1/2)^2 = 289/4
Step-by-step explanation:
x^2+x-72=0
Write like this:
(x + ___)^2 = ___
put 72 on other side
x^2 + x = 72
x^ + x + (1/4) = 72 + (1/4)
(x + 1/2)^2 = 289/4
x + (1/2) = 17/2
The answer is C. 207 cm. The formula to find the area of a triangle is 1/2 base times height. So the base is 9cm and the height is 7cm. Multiply them and you get 63, but you have to divide by 2 because the formula so you get 31.5 cm. Multiply that by 4 because there are four triangles. So you get 126 cm. Then to find the area of the square, you do s times s. Side times side so 9 times 9 is 81. Add the 81 and 126 together and your answer is 207. hope i helped ya!!
<em>Answer:</em>
47/48
<em>Explanation:</em>
Since 5 7/8 is so close to 6, it is easier to work this problem by considering the difference.
The serving size is 1/6 of the total amount, so you want to find ...
... (5 7/8) × (1/6)
Following the observation above, we can compute it as ...
... (6 - 1/8) × (1/6) = (6/6) - (1/8)×(1/6)
... = 1 - 1/48
... = <em>47/48</em>
