Answer:
700 pages
Step-by-step explanation:
I first found out how many pages were in 1% so I divided 28 by 4.

The given expression is
.
Put x = 2 in the above expression as follows :

Hence, the final answer is 16.
A). They are not similar, because 6/13 is not equal to 8/20
For triangles to be similar, the ratios of sides need to be the same (shortest to shortest, middle to middle, longest to longest). The shortest sides are 6 and 13, respectively, the middle ones are 8 and 20. Because 6/13 is not equal to 8/20, the triangles are not similar.
(1)
we are given

we can use quadratic formula


now, we can compare and find a , b and c
we get

now, we can plug these values into quadratic formula


we can simplify it



so, we will get solution
{−3+i, −3−i}.........Answer
(2)
we are given equation as

Since, Jamal solve this equation by completing square
so, firstly we will move constant term on right side
so, subtract both sides by 14


we can write

so, we will add both sides by 4^2

we get
..............Answer
It should be B I’m pretty sure
