Answer:
y=2x+4
Step-by-step explanation:
y=mx+b
y=2x+b
2=2(-1)+b
2=-2+b
+2 +2
b=4
y=2x+4
Answer:
The expression for area of rectangle in standard form is: 
Step-by-step explanation:
The area of rectangle is given by:

Here, in the question, we are given length and width of the rectangle
Length = 2x-3
Width = 5x+9
The area of the rectangle will be:

Hence,
The expression for area of rectangle in standard form is: 
A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
Answer:
the answer is B
as you can see the smaller triangular figure is in large by 4 so 6x4=36
Answer: x=-7/4+1/4√89 or x=-7/4+-1/4√89
