Answer: 4(d - 1)
Step-by-step explanation:
both terms in 4d - 4 have a common factor: 4. pull this 4 out of both factors in order to get 4(d - 1)
Here is you're answer:
In order to find the answer to this question you need to find the common denominator then add.
- Find the common denominator:
- Turn into mixed number:
Therefore you're answer is "1 1/4."

Answer:
d^2 - 14d + 49 = (d-7)(d-7).
Step-by-step explanation:
Given the expression is d^2 - 14d + 49.
d^2 - 14d + 49 = d^2 - 2*7*d + 7^2
We know the formula of square of difference as given below:-
x^2 - 2*x*y + y^2 = (x-y)^2
Using the above formula in the problem, here x = d and y = 7.
d^2 - 2*7*d + 7^2 = (d-7)^2
d^2 - 2*7*d + 7^2 = (d-7)(d-7)
So, d^2 - 14d + 49 = (d-7)(d-7).
