To find out the cups, total jug volume should be divided by 0.25 litre.
4.5/0.25
18 cups
Q1. The answer is 4(2x - 3)(2x + 1)
16x² – 16x – 12 = 4 * 4x² - 4 * 4x - 4 * 3 =
= 4(4x² - 4x - 3) =
= 4(4x² + 2x - 6x - 3) =
= 4(2x * 2x + 2x - (2x * 3 + 3)) =
= 4(2x(2x + 1) - (3(2x + 1))) =
= 4((2x + 1)(2x - 3)) =
= 4(2x - 3)(2x + 1)
Q2. The answer is 3(x + 8)(x - 1)
3x² + 21x – 24 = 3 * x² + 3 * 7x - 3 * 8 =
= 3(x² + 7x - 8) =
= 3(x *x - x + 8x - 8) =
= 3((x(x - 1) + 8(x - 1)) =
= 3(x + 8)(x - 1)
The surface area= 42.72 inches squared
All you got to do is find the area of each 6 sides the equation should be like this
3×6+3×6+6×.28+6×.28+.28×6+.28×6 and if you use a calculator your answer should be 42.72
4x+3x+1x=t, where x represents the number of people, and t represents the total cost.
So to solve it, it says Fitz and 3 friends so that’s four people, you’d substitute x for 4.
I hope this helps!
