The slope is 1/2 and the y-intercept is 3/2. those are the steps to graph the equation.
Area = length x width
60 = (x+5) (x-2)
60 = x^2 + 3x -10
Subtract 60 from both sides:
x^2 +3x -70 = 0
Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70
x = -10 and 7
Since the sides have to be a positive number we need to use 7
The length = x+5 = 7+5 = 12 cm
The width = x-2 = 7-2 = 5 cm
Answer:
12 (i think)
Step-by-step explanation:
so you see the problem the first problem is 3x-9. and you see 27
then you multiply 12 by 3 and you get 36 then you minus 36 by 9 and you get 27
We will find the volume by multiplying length * width * height, like this:
10 cm * 3 cm * 2 cm = 60 cm^3
For ml, when we talk about volume, we know that the 1 ml = 1 cm^2, so the answer for ml is 60ml.
Answer:
(2x+1)(x+3)
2x(x+3)+1(x+3)
2x2+6x+x+3
2x2+7x+3 (2x2 means two x square)
if you want you can also multiply 2x+3 by x+3
like this:
(2x+1)(x+3)
x(2x+1)+3(2x+1)
2x2+x+6x+3
2x2+7x+3 (2x2 means two x square)
They will both give you the same answer.
