Answer: The expression factors to (2x - 1)(5x + 4)
In a rectangle the area is L x W. So if we know the area is 10x^2 + 3x - 4, then all we have to do is factor it to find possible values for the L and W.
If you factor the expression by grouping, you will get (2x - 1) and (5x + 4).
Your questions asks for possible dimensions, you could give the two expressions as dimensions.
If you wanted to select a value for x, you could plug it in and get values that could be dimensions.
For example if you let x = 10, you would have a rectangle that has a width of 19 and a length of 54.
The answer is $2267.25
30.23*75=2267.25
Answer:
5/39
Step-by-step explanation:
2 1/6 = 13/2
5/6 divided by 13/2 = 5/6 multiplied by 2/13
5/6(2/13) = 5/39
so, your answer is 5/39
Answer: D and E
Step-by-step explanation:
To find this answer we want to get x by itself in the equation.
6x + 4 < 22
6x < 18
x < 3
So according to this the value of x has to be less than 3.
You can check your answer by substituting the values in for x.
6(0) + 4 < 22
4 < 22 is True
6(2) + 4 < 22
16 < 22 is True
6(3) + 4 < 22
22 < 22 False!
-2 - 3 -(-4)= -2 - 3 + 4
-2 - 3 + 4
-5 + 4
= -1
