I could probably answer this but....
I really can't read any of the question because it is sideways and I am on a computer... Sorry... Do you mind posting it again but in the right direction? Thanks :D (also on my computer, some on the stuff is cut off...)
Answer: x = 0 and x = 1Explanation:The image of the graph is in the figure attached.
There you can observe two intersection points which are (0,2) and (1,3), therefore the solutions are x = 0 and x = 1.
You can draw the graph by constructing a table with x from - 2 to 4, like this:
x f(x) = x + 2 g(x) = 2^x + 1
-2 -2 + 2 = 0 2^2 + 1 = 4 + 1 = 5
- 1 -1 + 2 = 1 2^1 + 1 = 2 + 1 = 3
0 0 + 2 = 2 2^0 + 1 = 1 + 1 = 2 => this is one solution
1 1+ 2 = 3 2^1 + 1 = 2 + 1 = 3 => this is the other solution
2 2 + 2 = 4 2^2 + 1 = 4 + 1 = 5

Answer:
Area of Rectangle = 28 cm²
Step-by-step explanation:
Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.
To find - What is the area of the shaded rectangle?
Solution -
The graph of the rectangle is as follows :
From the diagram, e can see that
Length of Rectangle = 7 units (cm)
Breadth of Rectangle = 4 units (cm)
We know that,
Area of Rectangle = Length × Breadth
= 7 × 4
= 28 cm²
⇒Area of Rectangle = 28 cm²
The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
