4x(y + 2)
mutiply the bracket by 4x
(4x)(y)(4x)(2)
4xy+8x
Answer : 4xy+8x
x^2-x-72 =0
find 2 numbers when multiplied = -72 and when added = 1
the zeros are 9 and -8
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Answer:
h = 
Step-by-step explanation:
bh-u+g=w original
bh= w+u-g move everything that does not have an h to other side
h = divide off b
