Answer:
A and B.
Step-by-step explanation:
4x^2 - 4x - 3 = 0
4x^2 + 2x - 6x - 3 = 0
2x(2x + 1) - 3(2x + 1) = 0
(2x - 3)(2x + 1) = 0
x = 3/2, -1/2.
Answer:
no solution
Step-by-step explanation:
2(x+2)=-6+2x
distribute the 2 in the parentheses: 2x+4=-6+2x
add the -6 to the other side to get rid of it on the side that it is on: 2x+10=2x
then subtract the 2x: 10=0x or 10=0
the equation is not solvable
Although the graph is not given in the option, so I would consider it from a different graph with the same question. The graph that represents the area of each rectangle in terms of the change in the length and width is the one with coordinate points located on the grid. The coordinate points on the form of (x,y) are represented as:
1. (0,40)
2. (1,45)
3. (2,47)
4. (8,25)
Hence,The graph with these coordinate points will be representing the situation.
Answer:
They are equal x = 110
Step-by-step explanation:
Exercise 4
A grow from 13.1 millions to 14.4 millions means to grow

millions. So, the question is: which percentage of 13.1 is 1.3? Well, we have to find a number x such that

Solving for x, you have

Exercise 5
27% is a bit more than 25%, which is a quarter. So, we expect to find a pie chart with one slice occupying roughly one quarter of the pie. The example that best suits this requirement is B (A is almost half, and C is less than one quarter).
